Hi Matthias, Thanks for your answer. I think that Hans has changed the way entries of mathmatrix are handled, that is they are now centered and this cannot be changed… However I think now that my way of using mathmatrix in order to get aligned cases, should be changed into the following: \definemathalignment[alignedcases] [n=3, align={right,left,left}, distance=3pt, left={\left\{}, right={\right.}, style=\displaystyle] Once this is done, the result is as expected since the math alignment environment accepts changing the alignment in each column. However the big problem is that one loses the left brace encompassing the displayed equations… I hope Hans will read this and help fix the issue… Best regards: OK %%% begin example-aligned-cases.tex \definemathalignment[alignedcases] [n=3, align={right,left,left}, distance=3pt, left={\left\{}, % this is not honoured… right={\right.}, style=\displaystyle] \starttext \startformula \startalignedcases \NC \partial_{tt} u - \Delta u + q(x) u \NC = 0 \NC \quad\mbox{in }\;(0,T)\times\Omega \NR \NC u(0,x) \NC = 0 \NC \quad \mbox{in }\; \Omega \NR \NC \partial_{t} u(0,x) \NC = 0 \NC \quad \mbox{in }\; \Omega \NR \NC {\partial u \over\partial{\bf n} } \NC = g(t,\sigma) \NC \quad \mbox{on }\; (0,T)\times\partial\Omega. \NR \stopalignedcases \stopformula \startformula \startalign[n=3,align={right,left,left}] \NC \partial_{tt} u - \Delta u + q(x) u \NC = 0 \NC \quad\mbox{in }\; (0,T)\times\Omega \NR \NC - \Delta v \NC = q(x) \partial_{t}u \NC \quad\mbox{in }\; \Omega \NR \stopalign \stopformula \startformula \startalignedcases \NC \partial_{tt} u - \Delta u + q(x) u \NC = 0 \NC \quad\mbox{in }\; (0,T)\times\Omega \NR \NC - \Delta v \NC = q(x) \partial_{t}u \NC \quad\mbox{in }\; \Omega \NR \stopalignedcases \stopformula \stoptext %%% end example-aligned-cases.tex

Same here. Curiously, the Garden version is ok, while the newest beta seems to make all alignments centered.

Minimal Example:

\starttext \startformula A=\startmathmatrix[align={right,right}] \NC1\NC-1\NR \NC-1\NC1\NR \stopmathmatrix \stopformula \stoptext

Hi everybody,

Does anyone have noticed that the mathalignment has changed its behaviour recently? I think a bug has managed to enter the environment which handles the mathalignment, at least since a few weeks ago. I did not report it earlier because I was traveling and did not have a stable internet access.

Here is a minimal example where on can see in the first displayed formula that the first and third column are centered while the first one shoud be right-aligned and the third one left-aligned. (Actually it seems that all columns are centered…) %%% begin pb-math-align.tex \definemathmatrix[alignedcases] [align={right,left,left}, distance=3pt, left={\left\{}, right={\right.}, style=\displaystyle]
