Re: [NTG-context] [Math in ConTeXt]
Thanks Otared for the offer to look into math issues.
Here are a few I noticed when TeXing an MK2 set of notes with MK4.
Matthias
\starttext
\startformula
\text{\bf R}^n = R^n ={\bf R}^n= \mathbb{R}^n
\stopformula
%spacing of exponent is in Mk4 wider than in Mk2
\startformula
\left| \int_{a_{i-1}}^b e^x\, dx \right|
\stopformula
% lower bound runs into \left|
% space between integral sign and integrand too wide
\startformula
r'=r''
\stopformula
This $\int_{a}^b e^x\, dx $ is not good.
% Inline math integrals need limits at the side. Spacing with lines below and
above is awkward otherwise.
\startformula
area(f) = \iint_{\Omega} |{f_u\times f_v}|\, du dv
\stopformula
% limit not centered over double integral
\placeformula[-]

Hi all,
After a series of exchanges on the list, on the topic of how mathematics
typesetting is and should be in ConTeXt, I am writing you this message to ask
all those who use ConTeXt to typeset mathematics and who encounter various
types of difficulties, or shortcomings, to send me their remarks, either on
list or off list.
I will check the problems with Aditya Mahajan and Mikael Sundqvist, and then
submit feature requests or bug reports to Hans and Aditya who will try to fix
the issues (I have asked these people about this, and they all agree…).
In order to help me manage efficiently the task, please add the following tag
[Math on ConTeXt]
to the Subject field of your message.
The issues which may be addressed are of the following categories:
1. Differences in the output of ConTeXt mkiv vs mkii (due to
differences in engine)
2. Differences in the output of ConTeXt mkiv vs LuaLaTeX + Opentype
math fonts (due to differences in macro package)
3. Differences in the output of ConTeXt mkiv vs PDFLaTeX + AMSMath (due
to differences in expectation)
4. Bug reports (regarding commands of plain TeX missing in ConTeXt, the
position of math accents, etc…)
Indeed some of the issues may have their origin in the fonts (therefore not
easy to fix thouroughly), but others may be fixed once the expectations are
clearly expressed.
As usual, please give minimal examples imbedded in
\starttext
………
\stoptext
so that we can test the issue you are reporting.
Thanks for your attention and cooperation,
Best regards: OK

Re: [NTG-context] Math Sets (ConTeXt port of braket.sty)
I uploaded the module to garden. I have only implemented scaling of single vertical bar (|). braket.sty also allows scaling of double vertical bar (||) and only treating the first | to be special. These are not implemented right now. In case someone needs them, let me know. The module is available from http://modules.contextgarden.net/mathsets Aditya I also need that. Thank you.

Re: [NTG-context] Math Sets (ConTeXt port of braket.sty)
Hi,
I find myself writing a lot of probability expressions where I want
the delimiters to scale automatically, and | (conditional sign) to
scale automatically, and the spacing around | to be correct. In LaTeX,
I used to use braket package to do this. Since moving to ConTeXt, I
was doing this by hand, but wring a lot of
\EXP\left\{ ... \,\middle\, ...\right\} and \Pr( ... \mid ...)
soon became a pain to read and write. So (thanks to Taco's first hand
knowledge of why TeX is Turing complete), I have written the following
macros:
\unprotect
\definesystemvariable {ms} % Math Set
\def\mathsetmiddle{\,\middle\mathsetparameter\c!middle\,}
\let\currentmathset\empty
\def\mathsetparameter#1%
{\executeifdefined{\??ms\currentmathset#1}{\executeifdefined{\??ms#1}\empty}}
\def\definemathset
{\dodoubleargument\dodefinemathset}
\def\dodefinemathset[#1][#2]%
{\getparameters[\??ms#1]
[\c!text=,\c!left={\{},\c!right={\}},\c!middle=\vert,#2]
\setvalue{#1}{\dododefinemathset[#1]}}
\def\dododefinemathset[#1]#2#%
{\begingroup
\def\currentmathset{#1}
\mathcode`\|32768
\let|\mathsetmiddle
\def\mathsetarguments{#2}
\dodododefinemathset}
\def\dodododefinemathset#1%
{\doifsomething{\mathsetparameter\c!text}
{\mathop{\mathsetparameter\c!text\mathsetarguments}}
\left\mathsetparameter\c!left#1\right\mathsetparameter\c!right
\endgroup}
\protect
which allows me to do
\definemathset[EXP][text={\mfunction{E}}]
\definemathset[PR][text={\mfunction{Pr}},left=(,right=)]
\starttext
Correct spacing around the vertical bar.
\startformula
\EXP{f(X) | Y} = \sum_{x} f(x) \PR{x|Y}
\stopformula
Correct scaling of delimiters (as correct as left and right give you)
\startformula
\EXP{\sum_z f(X,z) | Y} = \sum_{x,z} f(x,z) \PR{x,z|Y}
\stopformula
Correct handling of sub|/|super scripts
\startformula
\EXP_X{f(X) | Y} = \sum_{x} f(x) \PR{x|Y}
\stopformula
Is there anyone else interested in this kind of stuff? I have not
ported all the features of braket.sty, but only those that I needed.
Other should not be too difficult to port.
Hans and Taco: Does it make sense to add these to the core? If so, I
can polish the macros a bit (add a \setupmathsets command).
Aditya
I think I will need it near in the future. Thanks for nice the nice works.

[NTG-context] math in ConTeXt
is ConTeXt prepared for math?
I mean...can I do...
$\sum_{i=1}^{n}{x_{i}}$
as I used to in LaTeX ?
I don't make the \Sigma to be under and over characterised by i=1 and n.

With regard to mathematics ConTeXt can do all things which plain TeX can.

$\sum_{i=1}^{n}{x_{i}}$

Yes. For displaymath you can use plain TeX's $$\sum$$ or better
\placeformula
\startformula
\stopfromula
(LaTeX's \[ ... \] doesn't work.)
I don't make the \Sigma to be under and over characterised by i=1 and n.
In inline math you need \limits\sum if you want to have the i=1 below
and the n above the sum sign. If I'm not mistaken, LaTeX does the same.

Tobias

Hi Jose,
Indeed ConTeXt contains all the plain TeX commands and you can use
them (in this case \sum). So these formulas give what you want
$\sum_{i=1}^n x_i$ (for the summation)
$\prod_{i=1}^{i=n} (1+x_i)$ (for the product), and so on.
For the displayed version you can use either
$$\sum_{i=1}^n x_i$$
or
\startformula
\sum_{i=1}^n x_i
\stopformula

[NTG-context] math in context
I woul like to know where I may find a complete list of symbols like
$\Bbb{R}$
to use in context while I am typing maths.
The main hurdle that I have today in change my personal typset work from
latex to context is a lack of a reference manual in this area.
Do you know where I may find one?
Thanks in advance
