Currently, mathcases do not accept an align key. So matrix is the only

\definemathmatrix

should work.

Thanks for the fast help Aditya.

[NTG-context] Math align with \startcases
Hi everyone,
This question is primarily intended for Aditya… but I guess other
fellows on the list can also help me solve the following alignment
problem:
Is it possible to have an alignment like the rsult of the following
with \startcases...\stopcases?
\starttext
\startformula
\startmatrix[align={right,left,right},distance=3pt,left={\left\{},
right={\right.}]
\NC -\Delta u + g(u) \NC{} = f \NC \quad\mbox{in } \Omega\NR
\NC \displaystyle {\partial u \over \partial {\bf n} } \NC{} =
h(u) \NC \quad\mbox{on } \partial\Omega \NR
\stopmatrix
\stopformula
\stoptext
Actually I used to have such alignments with the following structure
(in good old plain TeX...):
\starttext
\startformula
\cases{
\eqalign{
-\Delta u + g(u) = f \cr
\displaystyle {\partial u \over \partial {\bf n} } = h(u) \cr
} \quad \eqalign{
\hbox{in } \Omega \cr
\vphantom{{\partial u \over \partial {\bf n} }} \hbox{on } \partial
\Omega \cr
}
}
\stopformula
\stoptext
(which gives approximately the same result as the first example above,
but clearly the math-alignment structure set up by Aditya and Hans is
much more elegant. (Although I prefer the vertical distance between
the lines obtained with my plain TeX structure: by the way is it
possible to fine tune such things in ConTeXt).
So my question is: whether one can use \startcases ...\stopcases
instead of \startmatrix ... \stopmatrix in order to obtain the result
of the plain TeX example?
Thanks in advance: OK

No, but there is not much difference between cases and matrix. Consider:
\definemathmatrix[alignedcase]
[align={right,left,right},distance=3pt,left={\left\{},
right={\right.},style=\displaystyle]
\starttext
\startformula
\startalignedcase
\NC -\Delta u + g(u) \NC{} = f \NC \quad\mbox{in } \Omega\NR
\NC {\partial u \over \partial {\bf n} } \NC{} = h(u) \NC \quad\mbox{on

\stopalignedcase

Hello David, sorry for the delay.
The problem is caused by \frac being defined in the newmat
module as
%D Better:
\def\frac#1#2{\mathematics{\genfrac{}{}{}\donothing{#1}{#2}}}
If you comment that line, it will compile flawlessly.
Hans, why would you want to allow \frac in text mode?
Changing it to \dfrac makes the input compile ok, but
typesets the cases in an ugly manner with really narrow
spacing.
(Yes.)
Is there some way of telling startcases/stopcases to behave in display

Yup, I just changed a couple of things and now we have a
