[NTG-context] Vertical lines in matrices

[Weber, Matthias]

Thanks Jeong,

I was aware of this. While there is no solution that adds vertical lines into matrices, one can juxtapose two (or more) of them with
properly chosen delimiters, like so:

\definemathmatrix
  [bvmatrix]
  [left={\left(\,},right={\ \right\vert}]

\definemathmatrix
  [rbmatrix]
  [left={\left.\,},right={\,\right)}]
  
\starttext
\startformula
\startbvmatrix
\NC 0 \NC  0\NC  0 \NR
\NC 1 \NC  0\NC  1 \NR
\stopbvmatrix
\startrbmatrix
\NC  0 \NR
\NC  1 \NR
\stoprbmatrix
\stopformula
\stoptext
