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
