[NTG-context] Trouble with this formula

[NTG-context] Trouble with this formula

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

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
