Re: [NTG-context] underbrace under matrix
Hi,
I will wait for the manual. With drawing commutative diagrams, I am sure
learning how to use MetaFun/MetaPost better might help.
Thanks for the fantastic work.

there is an extensive manual coming but you need to give us some time
(as it goes hand-in-hand with updating / extending some of the math
machinery)
if you have specific wishes, just let is know and we'll have a look if
it can somehow fit in

Re: [NTG-context] underbrace under matrix
Hello Mikael,
Thanks for your solution; it works just fine. I am not familiar with how you
defined the pmatrix. Any links to manuals to learn such definitions? Also, this
is the second thing I have tried to adapt from typesetting mathematics in plain
TeX that didn’t work. I tried to draw commutative diagrams some time back using
\diagram{…} which didn’t work(Got the idea from the book “A beginner’s book of
TeX” pg. 161 by Seroul et al ).
I guess what I am asking is that, what are the limits of what I can use
out-of-the-box from Tex when typesetting mathematics? I have read Aditya’s
ConTeXt-LaTeX tutorial which is fantastic. But the stuff illustrated there are
quite limited. Are there any materials I can read on this?
Thanks for your help.

Hi Jethro,
Temporary workaround: use the simplecommand.
\definemathmatrix[pmatrix][matrix:parentheses][
simplecommand=pmatrix,
]
\starttext
% \placeformula[-]
\startformula
\startalign
\NC A \NC = \underbrace{\pmatrix{5,5;-1,7}}_{B} \NR
\NC\NC = \underbrace{\pmatrix{2,1;4,2}}_{C} \NR
\stopalign
\stopformula
% \placeformula[-]
\startformula
A \alignhere=
\underbrace{\pmatrix{5,5;-1,7}}_{B}
\breakhere
=
\underbrace{\pmatrix{2,1;4,2}}_{C}
\stopformula
\stoptext
But the code you were using should in principle also work.
