Dear List, I am trying to get vertical (separating) lines into matrices, as is possible in tables: \starttext \startformula \left( \starttable[|c|c|c|] \NC 0 \NC 0\VL 0 \FR \NC 1 \NC 0\VL 1 \FR \stoptable \right) \stopformula \stoptext But my parentheses don’t fit, and I am not sure whether using tables in math mode is the proper way of doing things. \startmatrix seems to ignore a \VL. Any. suggestions? Thanks, Matthias
