Many thanks for your answer, I appreciate it!
If you look at the example below (output attached), you see that the
version with \bigl and \bigr has a different size than the other ones.
So my question boils down to: Is it possible, by using fences, to have the
same size as the \big, \Big, \bigg etc would give?
If not, is it possible to implement? I think it would make the already very
nice fencing system even more usable. The reason is to be able to use this
instead of not using fences at all in the few cases where the size from the
fencing is not optimal.

Many thanks, Hans! This works well and it makes the font usable.
I will try to contact the TeX Gyre project to report this issue in the font.

the fonts have bad glyph dimensions that assume italics always to be
applied (as in traditional tex fonts)
you can put this at the top of your file:
\definefontfeature[mathextra][collapseitalics=yes]
awaiting fixed fonts (if they never get fixed we can consider applying
this feature by default)
Ulrike Fischer reminded me in the StackExchange chat that not so long
time ago there was some similar issue with \mathcal P discussed on this
list. Is it the same problem? (The input $f \tracinglostchars=0
\Uchar"EEEFF$) indeed makes it look better between the $f$ and the
parenthesis.)

A small step in the right direction: Blackboard letters and calligraphic

{ name = "fourier-bb.tfm", vector = "tex-mb",

[NTG-context] Fourier and utopia
Dear Hans and dear list,
I try to use the fourier/utopia combination in mkiv (I used that
combination for my PhD thesis in mkii 10 years ago).
First of all, I have downloaded the fourier fonts from ctan at
https://ctan.org/tex-archive/fonts/fourier-GUT . The fonts are found by
mtxrun.
I have one folder containing type-fourier.mkiv, fourier-math.lfg and
testfile.tex. Everything seems to be found by the system, so the problem is
probably in my files somewhere. The resulting pdf after compiling
testfile.text is attached.
Any ideas of what I am missing?
Additionally, the fourier fonts come with fourier-bb.tfm (probably with
blackboard bold), fourier-mcl (probably so that one can use mathcal). Any
ideas on how to use them in the fourier-math.lfg file?
If more information is needed, then please tell me.

does not work on MacOS (which I am using). Can someone tell me which command I
need to use at MacOS (current version)?
Besides, Hans, I think it is a questionable decision to include the new
mechanism for primes in the beta but not the required LuaTeX version for them
to work correctly. I tried out the ConTeXt version „current“ (--context=current
downloading the standalone) and there the old bugs persist. That means that I
cannot use ConTeXt to typeset mathematics now, since no version works correctly
when primes are required (until I can handle it to compile LuaTeX 1.05, but I
think it would be much more comfortable the beta version of ConTeXt could run
using the LuaTeX version it provides on it’s own).

As far as I understand 1.05 will be out at the same time as the
context meeting takes place (Sepbember?).
For the thread, it was this one (that you participated in):
https://mailman.ntg.nl/pipermail/ntg-context/2017/088747.html . I
think the information you need is available there, but still:
I run linux (ubuntu), and these are the steps that made it work for me
(with help of luigi and Taco):
1) get the files
svn checkout --username anonsvn --password anonsvn
https://serveur-svn.lri.fr/svn/modhel/luatex/branches/experimental/
2) compile:
step into the folder experimental and run build.sh
3) copy the luatex binary to a place where it is found
I chose to replace the one from garden, and it seems to work.
Good luck!

Hi Mikael,
when will LuaTeX 1.05 be released? And how can I get the source for compilation
(and what exactly will I have to do to get everything to work)?
Besides: Do you have a link to the thread you are referring to?

I think this is intended (see the other thread). Hans decided to do
the primes differently, which means that they will look strange until
luatex 1.05 is out. You can compile luatex 1.05 yourself, and you will
see that the primes look OK. I attach a pdf result of your file,
compiled with 1.05.

[NTG-context] Bug regarding placement and size of primes
Dear Hans,
the newest beta (I have updated some hours ago) contains again some bugs
regarding the size and placement of primes. You can verify that by using the
following minimal example (created to show some older bugs being resolved
meanwhile):
%%%
\starttext
%
Compare $f'$ to $(f')$ and to $f''$, $(f'')$, $f^{''}$ and $(f^{''})$.
%
\startformula
%
\int\nolimits_a^b \bigl(\|f(x)\|\bigr)\, {\mathrm d}x
%
\stopformula
%
\stoptext
%%%
The output is attached. The primes are obviously rendered too small. And while
$f'$ seems to lead to a placement of the prime a little too low, $f^{'}$ seems
to cause the prime being placed too high.

Re: [NTG-context] No space after a closing delimiter
Hi Fabrice,
If you use your command \repere more often in the middle of a sentence you can
slightly modify the definition of your macro in order to have a space after
\repere. However, when your command is used at the end of a sentence, you have
to add \unskip after your command, as in the following example:
\define\repere{$\bigl(O\,;I,J\bigr)$\space}
\starttext
\dorecurse{2}{blabla} \repere \dorecurse{2}{blabla}
Déterminer la trajectoire dans le repère \repere\unskip.
\dorecurse{2}{Blabla} \repere\ \dorecurse{2}{blabla}
\dorecurse{2}{blabla} $\bigl(O\,;I,J\bigr)$ \dorecurse{2}{blabla}
\stoptext

Fantastic! Thank you Hans, it is way better than the old mechanism
\setmathfunctionstyle. Now I have a few suggestions to improve the
consistency of this new mechanism. First, I think this functionstyle key
a) should be better called 'mathlabelstyle';
No. The style applies to anything called using \mfunction{...}, so
functionstyle and functioncoloar are appropriate keys.
b) be default to \tf to make the FONT ALTERNATIVE always upright;
I disagree. The default should be \mathupright (as is the case in amstex
and latex, and probably also plaintex). We now have the option to change
it to \tf if desired.
c) be linked to this following new definition in math-ini.mkiv:
+ \unexpanded\def\mathlabel#1{\text{\mathlabelstyle #1}}
so that \mathlabel can be used for labeling math objects like functions but
ALSO for labeling variables with subscripts (e.g., \rho_{\mathlabel{air}}).
The hardcoded \text in the definition of \mathlabel is used here for these
5 reasons:
Hans already replied to that.
That \mathlabel should replace \mfunction which should be removed, and
\mfunctionlabeltext should be removed as well and one should directly use
the already defined \mathlabeltext instead, for these 3 reasons:
I strongly disagree to this. These are two completely different issues
(wanting a macro to tag multiletter variable names vs a macro to tag
log-like operators).
1. Every command containing the word 'labeltext' should not have a style
attached to it.
2. The word 'function' is misleading because \mfunction and
\mfunctionlabeltext do not create a \mathop atom and it makes the user
believe its usage is restricted for labeling functions while the command
should also be used for labeling variable with subscripts (e.g.,
\rho_{\mathlabel{air}} is far better than \rho_\mfunction{air}).
3. Using only \mathlabeltext with \setuplabeltext is also more consistent
with the current \labeltext that works with \setuplabeltext.
Thus the function definitions in math-def.mkiv should be changed:
- \definemathcommand [arccos] [nolop] {\mfunctionlabeltext{arccos}}
+ \definemathcommand [arccos] [nolop] {\mathlabel{\mathlabeltext{arccos}}}
etc.
I don't see the rationale for this.
And I think you should add in this file the definition of the differential
operator which is so widely used in mathematics, so that users have at
their disposal once for all a proper implementation of this operator and
don't have to make their own hack:
+ \definemathcommand[diff]{\mathop{\mathlabel{d}}\mathopen{}}
Note that there is no consensus on how the `d` in calculus should be
typeset. There are also \differentiald and \differentialD that map to
unicode slots.
\definemathcommand[arsinh][nolop]{\mathlabel{arsinh}}
\starttext
$\arsinh z = \ln\bigl(z + \sqrt{z^2 + 1}\bigr)$\par
$\rho_{\mathlabel{air}} = \frac{p}{R_{\mathlabel{specific}}T}$\par
\stoptext
\mfunction already does that.
I'll reply to the rest of the message later.

1. It CAN make the FONT STYLE adaptative to the surrounding style (if
the \mathlabelstyle inside—defined by the user in
\setupmathematics[mathlabelstyle=]—does not specify another FONT STYLE
like \rm, \ss or \tt).
2. It uses proper mathcodes (hyphens are not converted to minus binary
operators—useful if one wants to call its function or subscript
'low-frequency' for instance—, apostrophes are not converted to
primes—useful if one wants to call its function 'Riemann's function' for
instance).
3. It uses proper kerning (if one wants to call its function or
subscript 'WALL' for instance).
4. It uses proper ligatures (if one wants to call its function or
subscript 'efficiency' for instance).
5. It avoids the user having to add \kern\zeropoint to prevent vertical
alignment to the middle of the fraction bar when used inside \mathop for
one-character function names (if one wants to call its function 'd' for
instance).
That \mathlabel should replace \mfunction which should be removed, and
\mfunctionlabeltext should be removed as well and one should directly

3. Using only \mathlabeltext with \setuplabeltext is also more
consistent with the current \labeltext that works with \setuplabeltext.
mfunction will stay as it is also needed for tagged pdf and exporting
(basically it's an apply math function thing) so if something else is
needed another name/mechanism have to be made (with appropriate tagging)
the label itself is a special case as it's optional (and is just there
for cultural differences as not all countries use the english names)
so, \rho_{\mathlabel{air}} is something different then, some kind of
multi-character variable?
Thus the function definitions in math-def.mkiv should be changed:
- \definemathcommand [arccos] [nolop] {\mfunctionlabeltext{arccos}}

subscripts):
\definemathcommand[arsinh][nolop]{\mathlabel{arsinh}}

[NTG-context] Changing font for math function
Hans Hagen wrote:
for functions one can now use:
\setupmathematics
[functionstyle=\rm]
Fantastic! Thank you Hans, it is way better than the old mechanism
\setmathfunctionstyle. Now I have a few suggestions to improve the
consistency of this new mechanism. First, I think this functionstyle key
a) should be better called 'mathlabelstyle';
b) be default to \tf to make the FONT ALTERNATIVE always upright;
c) be linked to this following new definition in math-ini.mkiv:
+ \unexpanded\def\mathlabel#1{\text{\mathlabelstyle #1}}
so that \mathlabel can be used for labeling math objects like functions but
ALSO for labeling variables with subscripts (e.g., \rho_{\mathlabel{air}}).
The hardcoded \text in the definition of \mathlabel is used here for these
5 reasons:
1. It CAN make the FONT STYLE adaptative to the surrounding style (if the
\mathlabelstyle inside—defined by the user in
\setupmathematics[mathlabelstyle=]—does not specify another FONT STYLE like
\rm, \ss or \tt).
2. It uses proper mathcodes (hyphens are not converted to minus binary
operators—useful if one wants to call its function or subscript
'low-frequency' for instance—, apostrophes are not converted to
primes—useful if one wants to call its function 'Riemann's function' for
instance).
3. It uses proper kerning (if one wants to call its function or subscript
'WALL' for instance).
4. It uses proper ligatures (if one wants to call its function or subscript
'efficiency' for instance).
5. It avoids the user having to add \kern\zeropoint to prevent vertical
alignment to the middle of the fraction bar when used inside \mathop for
one-character function names (if one wants to call its function 'd' for
instance).
That \mathlabel should replace \mfunction which should be removed, and
\mfunctionlabeltext should be removed as well and one should directly use
the already defined \mathlabeltext instead, for these 3 reasons:
1. Every command containing the word 'labeltext' should not have a style
attached to it.
2. The word 'function' is misleading because \mfunction and
\mfunctionlabeltext do not create a \mathop atom and it makes the user
believe its usage is restricted for labeling functions while the command
should also be used for labeling variable with subscripts (e.g.,
\rho_{\mathlabel{air}} is far better than \rho_\mfunction{air}).
3. Using only \mathlabeltext with \setuplabeltext is also more consistent
with the current \labeltext that works with \setuplabeltext.
Thus the function definitions in math-def.mkiv should be changed:
- \definemathcommand [arccos] [nolop] {\mfunctionlabeltext{arccos}}
+ \definemathcommand [arccos] [nolop] {\mathlabel{\mathlabeltext{arccos}}}
etc.
And I think you should add in this file the definition of the differential
operator which is so widely used in mathematics, so that users have at
their disposal once for all a proper implementation of this operator and
don't have to make their own hack:
+ \definemathcommand[diff]{\mathop{\mathlabel{d}}\mathopen{}}
With this new \mathlabel command, the user now have a convenient and
consistent way to label its math objets (functions and variables with
subscripts):
\definemathcommand[arsinh][nolop]{\mathlabel{arsinh}}
\starttext
$\arsinh z = \ln\bigl(z + \sqrt{z^2 + 1}\bigr)$\par
$\rho_{\mathlabel{air}} = \frac{p}{R_{\mathlabel{specific}}T}$\par

Fine. In principal I've nothing against typing || for double bars
(even though people moving from TeX/LaTeX probably will be used to |
for one bar and \| for two bars). Some questions:
* Can one expect to get the right (that is the same as \Vert gives)
spacing by typing || (two bars) in ConTeXt in the future?
* Sometimes one would like to write absoulte value of z times absolute
value of w, i.e. |z| times |w|. What if one writes |z||w|, will the
double bar in the middle be equivalent to \Vert? (That is not wanted)
* Will it be possible to write \Bigl|| and \Bigr|| to scale both bars
to other sizes?
* What if one would like to have three bars with the same spacing
between the bars as in \Vert?

\Vert and not |. This is not so (see the attached file). Moreover, it
is not possible to do \bigl\Vert right now to get a bigger ||.
i've added double bars so this works:
$\biggl\Vert x^n\biggr\Vert$
$\biggl{||} x^n\biggr{||}$
$\biggl|\biggl| x^n\biggr|\biggr|$
there will be a new beta later today or tomorrow

Thanks for you answer and explanation. Is there a reason why you do
not add \| to get double bars? This is the way it is done in LaTeX
(OK, not really an argument). I'm just curious.

Ok Hans, with the beta from yesterday the absolute values change size,
but there are some problems still:
1) The absolute value bars are not just straight lines when using
\big and friends, but som kind of line that is thicker in the middle.
(zoom i on attached pdf)
2) The horizontal spacing in the \big version seems to be bigger than
for the \bigl/\bigr version (and similar for \Big vs \Bigl/\Bigr). I'd
expect the same spacing (the l and r are just there for the writer to
easily see what is left and what is right).
3) I'd expect that \| gives double bars, like the || one get from
\Vert and not |. This is not so (see the attached file). Moreover, it
is not possible to do \bigl\Vert right now to get a bigger ||.

I don't know how to do this. should behave like a rel without a \left, and
like a delimited with \left.
I have tried to use

rbrace!!. Probabably you want rangle. You can change the order of the two,
and then will map to rangle, but you will have to use \gt to get the
relation symbol.

The attached patch gives a working solution for lmmath but does not work
with cambria. I don't know if the latter is a fault of context mkiv or
luatex.
In any case, this is a kludge as we have to define a dummy name. It will
be better if we could just say name=false. Currently, if I use name=false,
\left gives an error.

Re: [NTG-context] Indent after formula in enumeration

Thanks Aditya, but it does not work what it should?

\stopformula%
per a alguns $x_i, y_j \in F(A)$, $r_i, s_j \in R$, on aquestes

I have that per a alguns is indenting but on is not.
Why?
Xan.
PS: Please, CCme
I have
%Indentation
\setupheads[indentnext=yes]
\setupindenting[yes,small,first]
\setupformulae[indentnext=yes]
in headers.
if I put setupformulae[identnext=yes] and ident=yes for enumerations
_always_ have indenting after formula even if the text is following.

with texlive 2008 it works just fine, i've attached the output of the

\subsubsection[ksec:paulitvad]{The Pauli operator in $\mathbb{R}^2$}
A charged spin $1/2$ particle is described by the Pauli Hamiltonian, which acts in $L_2(\mathbb{R}^2)\otimes \mathbb{C}^2$, and is formally defined as
\placeformula[keq:pauli]
\startformula
\pauli =
\startpmatrix
\NC H-\frac{g}{2}B \NC 0 \NR
\NC 0 \NC H+\frac{g}{2}B\NR
\stoppmatrix.
\stopformula
Here $H$ is the two-dimensional Schrödinger Hamiltonian $H=(-i\nabla -\vec{a})^2$, $B$ is the magnetic field (In two dimensions we identify the two-form and the coefficient function), and $g$ is the {\em gyromagnetic ratio}. We identify the real point $(x^1,x^2)$ with the complex number $z=x^1+ix^2$, and denote a scalar potential of $B$ by $W$,
\startformula
-\Delta W = B.
\stopformula
We set $\Pi_j = -i\PD{}{x^j}-a_j$ and
\startformula
\ann = \Pi_1 - i \Pi_2,\quad \cre = \Pi_1 + i\Pi_2,
\stopformula
and note that
\placeformula[keq:komm]
\startformula
\ann\cre=\cre\ann+2B,\quad H=\cre\ann+B=\ann\cre-B.
\stopformula
From~\eqref[keq:pauli] and~\eqref[keq:komm] we get
\placeformula[keq:paulig]
\startformula
\pauli =
\startpmatrix
\NC \cre\ann-\frac{g-2}{2}B \NC 0 \NR
\NC 0 \NC \ann\cre+\frac{g-2}{2}B\NR
\stoppmatrix.
\stopformula
The number $\frac{g-2}{2}$ is called the {\em anomaly factor} of the magnetic moment. Experiments give an anomaly factor of $0.00159$ for the electron~\cite[bovo]. We assume that $g=2$, which is the simplest case. Thus, the Pauli Hamiltonian we study in this thesis is formally defined by
\placeformula[keq:pauliw]
\startformula
\pauli =
\startpmatrix
\NC \cre\ann \NC 0 \NR
\NC 0 \NC \ann\cre\NR
\stoppmatrix.
\stopformula
The Pauli operator can be written as the square of the Dirac operator
\placeformula[keq:paulia]
\startformula
\pauli = \dirac^2 = \Bigl(\sum_{j=1}^2 \sigma_j\big(-i\PD{}{x^j}-a_j\big)\Bigr)^2 =
\startpmatrix
\NC 0 \NC \cre \NR
\NC \ann \NC 0\NR
\stoppmatrix^2
\stopformula
from which it follows that it is a non-negative operator. Now let us be more precise about the domains. As in the case of the Schrödinger Hamiltonian there is a problem in defining the Pauli Hamiltonian if the magnetic field is too singular. The quadratic form corresponding to $\pauli$ is given by
\placeformula[keq:pform]
\startformula
\pform(\psi,\psi)= \int_{\mathbb{R}^2} \Big|\sum_{j=1}^2 \sigma_j\big(-i\PD{}{x^j}-a_j\big)\psi\Big|^2\ed m(x).
\stopformula
If $\vec{a}\in L_{2,\text{loc}}(\mathbb{R}^2)\otimes \mathbb{R}^2$ then $\pform(\psi,\psi)$ makes sense for $\psi\in C_0^\infty(\mathbb{R}^2)\otimes \mathbb{C}^2$. We define the {\em minimal} Pauli form $\pform_{\text{min}}$ as
\startformula
\startalign
\NC \dom(\pform_{\text{min}}) \NC = C_0^\infty(\mathbb{R}^2)\otimes \mathbb{C}^2;\NR
\NC \pform_{\text{min}}(\psi,\psi) \NC = \pform(\psi,\psi),\quad \psi\in\dom(\pform_{\text{min}}).\NR
\stopalign
\stopformula
It is closable and thus a self-adjoint operator $\pauli_{\text{min}}$ can be defined. We also define the {\em maximal} Pauli form $\pform_{\text{max}}$ as
\placeformula
\startformula
\startalign
\NC \dom(\pform_{\text{max}}) \NC = \bigl\{\,\psi\in L_2(\mathbb{R}^2)\otimes \mathbb{C}^2\bigm| \pform

Re: [NTG-context] Is there a mathematica typesetting manual for ConTeXt ?
I'm affraid I'm too late already, but I'm sending this anyway. The
lines you sent as an example have two pecculiarities:
- bad alignment
- too short arrows
I managed to solve the first problem -- alignment (with some
cheating, using TeXBOOK), but I have no idea how to extend
\downharpoonright for example and \longrightleftharpoons also don't
look as they should.
In plain TeX it is possible to say \big\downarrow or \Bigg\downarrow
and the arrow is as long as desired. I neither do understand how this
mechanism works nor did I found out how \downharpoonright was defined
(which font, ...).
Does any Font/TeXnician have any idea how to make \Big\updownharpoons work?
xiaojf said this at Sat, 14 May 2005 21:36:45 +0800:
Hi,
I can code the cycle in ConTeXt,but it's too ugly and I will try to

There is a similar example in The TeXbook(example 18.46).
You can try the follow code:
$$\def\normalbaselines{\baselineskip20pt\lineskip3pt \lineskiplimit3pt }
these are just a few local space adjustment, not important to
undestand the content.
\def\mapright#1{\smash{
\mathop{\longrightarrow}\limits^{#1}}}
define a command \mapright:
- \mathop makes \longrightarror behave in a similar way as big
operators like \sum, \int, ...
- \limits makes the ^{#1} appear centered above the arrow smaller than
the rest (the same as super/sub-scripts)
\def\mapdown#1{\Big\downarrow
\rlap{$\vcenter{\hbox{$\scriptstyle#1$}}$}}
define a command \mapdown:
- \Big makes the \downarrow longer (no idea how to make something
similar for a harpoon)
- \rlap places the argument to the right of the arrow with virtual box
width 0 (so that the arrow can be centered)
- $\vcenter{\hbox{...}}$ takes care of vertical centering
- $\scriptstyle #1$ is a compensation for ^{#1} above and takes care
that the argument becomes smaller. Note that if equation is not
typeset in \displaystyle, than it may be that this is not of the same
size as the argument in \mapright

Since i'm just a newbie of TeX, I don't really understand the first a few
lines
of the solution. I still need some learning and practice :)
I hope I explained at least a little bit of it.
So here's my proposal (not perfect yet):
\usemodule[nath]
% is there any other way to use local variables than \unprotect?
% I also had to define [EMAIL PROTECTED] once more, which is not very elegant,
% but I don't know any other way
\unprotect
[EMAIL PROTECTED]
% The TeXBOOK, page 358, modified \longrightarrow
% for some reason, the harpoon and line are not 100% perfectly joined
\def\longrightharpoonup{\relbar\joinrel\rightharpoonup}
\def\longleftharpoondown{\leftharpoondown\joinrel\relbar}
% slightly longer line which didn't work: it this looks ugly
% probably a definition, similar as in \overrightarrow
% would help producing longer harpoons
%
% \def\longrightharpoonup{\relbar\joinrel\relbar\joinrel\rightharpoonup}
% \def\longleftharpoondown{\leftharpoondown\joinrel\relbar\joinrel\relbar}
% The TeXBOOK, page 361m modified \rightleftharpoons
[EMAIL PROTECTED]

% here are four different placements of \Delta G_i,

Re: Re: [NTG-context] Is there a mathematica typesetting manual for ConTeXt ?
=== 2005-05-14 13:31:00 You worte===
xiaojf said this at Sat, 14 May 2005 19:49:02 +0800:
The double-, triple-, and quadruple-integrals (\nt) are undefined in
basic ConTeXt's math.
I must say thank you very very much!
In fact I've been looking for \iint in ConTeXt in the last two days -_-
so i'll try to use \int\!\!\!\int instead of looking for a ConTeXt
implementation :)
I met another problem today. Since there are not as many arrows in
ConTeXt as there
in AMS-LaTeX,I don't konw how to type the formula in the attached picture
which will
be referred in my presentation next Monday.
Hello, Xiao.
I'm glad I could help: I'm learning these advanced requirements as I go
along. My personal mathematics needs are much more modest.
I wouldn't give up on ConTeXt just yet. Try:
\loadmapfile[original-ams-base]
\starttext
\showmathcharacters
Note the \formula{\rightleftharpoons} and
\formula{\upharpoonleft\!\downharpoonright}.
\stoptext
Do you know how you would code that cycle in (AMS)LaTeX?
Hi,
I can code the cycle in ConTeXt,but it's too ugly and I will try to improve it.
here is my code:
\starttext
\placeformula
\startformula
\matrix{A+B{\Delta G_1\atop\rightleftharpoons}AB\cr
\Delta G_3\!\!\upharpoonleft\!\downharpoonright
\upharpoonleft\!\downharpoonright\!\!\Delta G_4\cr
A'+B{\rightleftharpoons\atop\Delta G_2}A'B\cr}
\stopformula
\stoptext
There is a similar example in The TeXbook(example 18.46).
You can try the follow code:
$$\def\normalbaselines{\baselineskip20pt
\lineskip3pt \lineskiplimit3pt }
\def\mapright#1{\smash{
\mathop{\longrightarrow}\limits^{#1}}}
\def\mapdown#1{\Big\downarrow
\rlap{$\vcenter{\hbox{$\scriptstyle#1$}}$}}
\matrix{0\cr
\mapdown{}\cr
0\mapright{}{\cal O}_C\mapright\iota
\cal E\mapright\rho\cal L\mapright{}0\cr
\Big\Vert\mapdown\phi\mapdown\psi\cr
0\mapright{}{\cal O}_C\mapright{}
\pi_*{\cal O}_D\mapright\delta
R^1f_*{\cal O}_V(-D)\mapright{}0\cr
\mapdown{\theta_i\otimes\gamma^{-1}}\cr
\hidewidth R^1f_*\bigl({\cal O}
_V(-iM)\bigr)\otimes\gamma^{-1}\hidewidth\cr
\mapdown{}\cr
0\cr}$$
Since i'm just a newbie of TeX, I don't really understand the first a few lines
of the solution. I still need some learning and practice :)

[NTG-context] Matrix or array and \Bigl
Hi everyone,
a quick question:
how can I deal with matrices in ConTeXt ?
I tried to use what is described in the wiki as a form of dealing with the
latex environment convention and importing the amsl package...
\def\begin#1{%
\csname start#1\endcsname}
\def\end#1{%
\csname stop#1\endcsname}
...
\usemodule[amsl]
then I tried:
\begin{array}{c} a + b \\ c + d \end{array}
and also,
does the tex sequence \left{ work ok in ConTeXt?
Thanks in advance.
Regards to everyone.
Jose Ignacio Marín
