Matrices can also be entered using MATLAB syntax (you need to specify a
`simplecommand` for mathmatrix:
\definemathmatrix[bmatrix][matrix:brackets][simplecommand=BMATRIX]
\starttext
Default style:
\startformula
\startbmatrix
\NC 1 \NC 2 \NC 3 \NR
\NC 4 \NC 5 \NC 6 \NR
\NC 7 \NC 8 \NC 9 \NR
\stopbmatrix
\stopformula
Compact style:
\startformula
\BMATRIX{1, 2, 3; 4, 5, 6; 7, 8, 9}
\stopformula
\stoptext
I'd say this is more compact (and natural) than amsmath :-)

Re: [NTG-context] Converting from LaTeX for PDF accessibility tagging?
Thank you very much - I think the problem was with a LaTeX "align" environment which pandoc translated into a setting which ConTeXt didn't recognize. These equations were monsters, so I'll try with simpler equations to give you an idea. But in fact what you say makes perfect sense, and I'll go back and read through the mathematics document again, and more closely this time! (For matrices and arrays I still prefer the neat LaTeX implementation, but maybe that's simply my general unfamiliarity with ConTeXt.) Thanks again!

[NTG-context] Commands with arguments before in ConTeXt
I've read the following is not possible in TeX
\def#1\macro{blabla#1}
where arguments come before. The only partial exceptions are commands like
\atop or \over, which are in fact primitives. Is there a way to do this in
ConTeXt?
Could it be a feature request for LuaMetaTeX? I've seen Hans experimenting
a lot with new primitives and new possibilities for arguments, like #0 and
co., so I ask in case it's not too nonsensical to propose it. Regards
Jairo :)

[NTG-context] Fwd: Continued fractions in ConTeXt
Hi list! I've tried adapting the following code for continued fractions:
%https://tex.stackexchange.com/questions/73195/how-to-typeset-a-continued-fraction-in-the-following-format
\documentclass{article}\usepackage{amsmath}
\begin{document}\newcommand*{\cofrac}[2]{%
{%
\rlap{$\dfrac{1}{\phantom{#1}}$}%
\genfrac{}{}{0pt}{0}{}{#1+#2}%
}%}\[
a_0 +
\cofrac{a_1}{
\cofrac{a_2}{
\cofrac{a_3}{
\genfrac{}{}{0pt}{0}{}{\ddots}
}}}\]\end{document}
As I could read from the mailing list, ConTeXt no longer supports
\genfrac, so I've tried
the following using \definemathfraction
\definemathfraction[gefrac][cfrac]
\setupmathfraction[gefrac][rule=no]
\def\cofrac#1#2{%
{%
\rlap{\cfrac{1}{\displaystyle\phantom{#1}}}%
\gefrac{}{\displaystyle\gefrac{#1+}{}#2}%
}%
}
\def\cofracnorule#1#2{%
{%
\rlap{\gefrac{\displaystyle\phantom{1}}{\displaystyle\phantom{#1}}}%
\gefrac{}{\displaystyle\gefrac{#1}{}#2}%
}%
}
\def\endfrac#1{\cofracnorule{#1}{\phantom{1}}}
\startTEXpage
\startplacefigure[location=force,number=no]
\externalfigure[cofrac.png]
\stopplacefigure
\startformula
\alpha +
\cofrac{\alpha'}{\cofrac{\alpha''}{\cofrac{\alpha'''}{{\endfrac{\ddots}
\frac{1}{\alpha'''}
\stopformula
\stopTEXpage
Mmm, superscripts and fraction rules superpose, so indeed something is
wrong. Any ideas or references to a better result?
I've attached the expected result (it's from Legendre's Théorie des
nombres) and a normal fraction for comparison.
Thank you very much.

[NTG-context] Converting from LaTeX for PDF accessibility tagging?
Hello, I tried ConTeXt a few years ago, then gave up on it because of its wordiness and verbosity. The 2006 article on creating AMSTeX output in ConTeXt at https://www.ntg.nl/maps/34/06.pdf shows exactly what I mean: the LaTeX commands are small and neat; the ConTeXt commands are not. However, I need now to use ConTeXt for accessibility tagging, so I'm prepared to give it another try. And this means converting some LaTeX documents into ConTeXt. Is there a better way than using pandoc? I ran a LaTeX document through pandoc, but the result is certainly not fully "ConTeXt compliant", and generates errors instead of compiling. I can get easily lost on the ConTeXt site: the documentation is there in plenty, but seems hard to search. The main problem for me is mathematics and alignment: not just for equations, but for matrices and arrays. What I'd love - if it exists - is a document showing how to rewrite LaTeX into ConTeXt. Something like the above document, which is now 14 years old. I also notice that much of the contextgarden wiki is outdated. For example, on the use of ConTeXt in MikTeX, we read "As of end of June 2011 MikTeX is still (or again) non-functional." I'm aware that all of this is the work of dedicated and unpaid volunteers, so this is not a complaint! Just an observation. Anyway, as I say, my main issues are converting LaTeX into ConTeXt. and dealing with mathematics. Any pointers would be gratefully received!

You have two options:
