Hi Otared,
Thank you very much.
I used your example to write the following macros. They are far from perfect but suit my needs. A few days ago, Hans warned not to use \noalign in LMTX, so I used the trick he gave to the list even if I don't really understand it.
=== LMTX version ============
%D \macros{HR, VR}
%D \type{\HR} draws a horizontal rule between two rows of a matrix
%D \type{\VR} is used in place of \type{\NC} to draw a vertical rule between two columns of a matrix
%D each macro takes an optional parameter giving the rule dimensions
%D Example
%D \type{\startmatrix \NC A \VR[depth 2mm] B \NR \HR[height 0.6pt] \NC C \VR D \NR \stopmatrix}
\pushoverloadmode
\noaligned\tolerant\protected\def\HR[#1]{\noalign{\hrule #1}}
\popoverloadmode
\def\VR{\dosingleempty\doVR}
\def\doVR[#1]{\NC \hskip-0.5em \vrule #1 \hskip-0.5em \NC}
===========================
=== MkIV version ============
%D \macros{HR, VR}
%D \type{\HR} draws a horizontal rule between two rows of a matrix
%D \type{\VR} is used in place of \type{\NC} to draw a vertical rule between two columns of a matrix
%D it takes an optional parameter giving the rule dimensions
%D Example
%D \type{\startmatrix \NC A \VR[depth 2mm] B \NR \HR \NC C \VR D \NR \stopmatrix}
\def\HR{\noalign{\hrule}}
\def\VR{\dosingleempty\doVR}
\def\doVR[#1]{\NC \hskip-0.5em \vrule #1 \hskip-0.5em \NC}
===========================
For the MkIV version I haven't been able to add an optional parameter to \HR the code
\def\HR{\dosingleempty\doHR}
\def\doHR[#1]{\noalign{\hrule #1}}
complains about "Misplaced \noalign"
Best regards,
