should be ok now

Thank you Hans for this fix!

There seems to be, however, still a minor issue with a more complete MWE: \math{ \startmatrix \NC A \NC B \NR \NC C \NC D \NR \stopmatrix}

can you test with

\def\math_matrix_process#1#2% {\forgettagging % otherwise dummy mrows and such \dowithnextbox {\scratchdimen\dimexpr(\nextboxdp-\nextboxht)/2 \ifcase#2\or+\mathaxisheight\textfont2\fi\relax

\ifcase#1\relax\or\lower\scratchdimen\or\or\raise\scratchdimen\fi\hbox\bgroup \normalstartimath \mathmatrixparameter\c!left \vcenter{\unvbox\nextbox}% \mathmatrixparameter\c!right \normalstopimath \egroup}% \vbox}

Indeed, this is much better! Thank you! I recommend to include this as a patch in ConTeXt. However: Testing never stops ;-) I have the following MWE: \definemathmatrix[pmatrix][left={\left(},right={\right)}] \math{ \startpmatrix \NC A \NC B \NR \NC C \NC D \NR \stoppmatrix} This (including your suggested fix) results in the following structure tree: <document> |-<math> | '-<mrow> | '-<mrow> | '-<mfenced> | '-<mrow> '-<math> '-<mtable> |-<mtr> | |-<mtd> | | '-<math> | | '-<mrow> | | '-<mi> | | '-"A" | '-<mtd> | '-<math> | '-<mrow> | '-<mi> | '-"B" '-<mtr> |-<mtd> | '-<math> | '-<mrow> | '-<mi> | '-"C" '-<mtd> '-<math> '-<mrow> '-<mi> '-"D" I think that the <mtable> should be located within the <mfenced>, shouldn't it? Cheers, Christoph
