I think in this case it is better to use a mathsimplealign instead of a matrix. \definemathsimplealign[pdeproblem][ left={\startmathfenced[cases]}, right=\stopmathfenced, align={1:right,2:left,3:left}, strut=yes, ] \definemathsimplealign[collected][ left={\startmathfenced[sesac]}, right=\stopmathfenced, align={1:right,2:left,3:left}, strut=yes, ] \starttext \placeformula \startformula \startpdeproblem \NC - \Delta u \NC = 0 \NC \qquad\text{in } \Omega \NR \NC \frac{\partial u}{\partial {\bi n}} \NC = V u + \phi \NC \qquad\text{on } \partial\Omega \NR \stoppdeproblem \stopformula \placeformula \startformula \startcollected \NC - \Delta u \NC = 0 \NC \qquad\text{in } \Omega \NR \NC \frac{\partial u}{\partial {\bi n}} \NC = V u + \phi \NC \qquad\text{on } \partial\Omega \NR \stopcollected \stopformula \stoptext Best, Mikael ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://www.ntg.nl/mailman/listinfo/ntg-context webpage : https://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : https://contextgarden.net ___________________________________________________________________________________
