It is of the essence for a series of Powerpoint slides I am preparing, wheein these formulae must be placed as individual pictures.
you can patch pmatrix:
\unexpanded\def\pmatrix#1%
{\left(\matrix{#1}\right)}
(i'll make the lot unexpandable)
btw, for large chunks you can consider using setups
\startsetups lots-of-math
\stopsetups
... \textext("\setup[lots-of-math]")
