Dear List,
I have a trouble with this formula, because, I would like to have c + d also in the matrix, but it is not working.
\starttext
\startformula
\startmathmatrix[fences=doublebar]
\pmatrix
{ a + b\NR}
{ c + d \NR}
\stopmathmatrix
\stopformula
\stoptext
And another question too:
I would like to need the command \parallel, instead of the fences, how can I make them big?
Many thanks
Uschi
