Hello,

I have problems with typesetting of  matrices with delimiters. I need the same functionality like in the following LaTeX example:

\begin{displaymath}
\left(\begin{array}{c|c}
 1 & 2 \\

\hline
3 & 4
\end{array}\right)
\end{displaymath}

but in ConTeXt I can't find method how to do that. My best result is 

\startformula
\startmathmatrix[left={\left(\,},right={\,\right)}]

\NC 1   \NC \vl  \NC 2   \NR
\NC \hl \NC \vl  \NC \hl \NR
\NC 3   \NC \vl  \NC 4   \NR
\stopmathmatrix
\stopformula

But the result is not ok.

In addition, I would prefer dashed lines.

Thanks,


Jiri Cigler
