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?
1. Use ; the separate lines with simple matrices. 2. Use \NR to end lines when you use the matrix environment. 3. You can use \vvmatrix. \starttext \startformula \startmathmatrix[fences=doublebar] \pmatrix{a+b;c+d}\NR \stopmathmatrix \stopformula \startformula \vvmatrix{\pmatrix{a+b;c+d}} \stopformula \stoptext Wolfgang
