Re: [NTG-context] Simple command with variable number of arguments

23 May 2014

      Thanks Otared,

that looks very promising. My attempt to wrap the arguments with \NC \NR fails, though.
It looks like only the first argument is used, and I am clearly missing something.
Also, I’d like to use the example you posted but without the last comma so that in the example below
I get (4,5) instead of (4,5,).

Matthias

\definemathmatrix
  [pmatrix]
  [left={\left(\,},right={\,\right)}]

\def\docolumnvector#1{\NC#1\NR}

\def\columnvector#1
{\startpmatrix
\processcommalist[#1]\docolumnvector
\stoppmatrix}

\def\dorowvector#1{#1,}

\def\rowvector#1
{\startpmatrix
\processcommalist[#1]\dorowvector
\stoppmatrix}

\starttext

\startformula
\columnvector{1,2,3}
\stopformula

\startformula
\rowvector{4,5}
\stopformula

\stoptext

Hi,
Some time ago Wolfgang S. gave a solution to a similar problem: maybe this can help you.
%%%% begin
\def\somemacro#1%
 {\def\dosomemacro##1{Execute ##1, }%
  \processcommalist[#1]\dosomemacro}
\starttext
\somemacro{A,B,C}
\somemacro{E,F}
\stoptext
%%%% end
Best regards: OK

Dear All,
I would like to define a command that expands
\vector{2,4} % or vector[2,4] if that’s easier
to
\startpmatrix
\NC 2 \NR
\NC 4 \NR
\stoppmatrix
and more generally
\vector{2,4,1,7}
to
\startpmatrix
\NC 2 \NR
\NC 4 \NR
\NC 1 \NR
\NC 7 \NR
\stoppmatrix
Any hints how to achieve this?
Thanks,
Matthias
