Ignore my other message, this is even better: \definemathmatrix [pmatrix] [matrix:parentheses] [simplecommand=pmatrix] \definemathmatrix [bmatrix] [matrix:brackets] [simplecommand=bmatrix] \definemathmatrix [vmatrix] [matrix:bars] [simplecommand=vmatrix] \definemathmatrix [Vmatrix] [left={\left\lVert\mskip\thinmuskip}, right={\mskip\thinmuskip\right\rVert}, align=middle, simplecommand=Vmatrix] \starttext \startformula \startpmatrix \NC A \NC B \NR \NC C \NC D \NR \stoppmatrix \quad \startbmatrix \NC A \NC B \NR \NC C \NC D \NR \stopbmatrix \quad \startvmatrix \NC A \NC B \NR \NC C \NC D \NR \stopvmatrix \quad \startVmatrix \NC A \NC B \NR \NC C \NC D \NR \stopVmatrix \stopformula \startformula \pmatrix{A, B; C, D} \quad \bmatrix{A, B; C, D} \quad \vmatrix{A, B; C, D} \quad \Vmatrix{A, B; C, D} \stopformula \stoptext > > By the way, I think it is critical to set > \setupmathematics[ampersand=normal] > to use \matrix above but I can't find this setting in ma-cb-en.pdf > It is great if this is added in ma-cb-en.pdf > > > ___________________________________________________________________________________ > If your question is of interest to others as well, please add an entry to the > Wiki! > > maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context > webpage : http://www.pragma-ade.nl / http://context.aanhet.net > archive : https://bitbucket.org/phg/context-mirror/commits/ > wiki : http://contextgarden.net > ___________________________________________________________________________________ > ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___________________________________________________________________________________
