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,
\definemathmatrix [pmatrix] [left={\left(\,},right={\,\right)}] \startluacode document = document or {} document.matthias = document.matthias or {} local function lua_columnvector(a) context.startpmatrix() for i,v in ipairs(a) do context.NC() context(tostring(v)) context.NR() end context.stoppmatrix() end document.matthias.lua_columnvector = document.matthias.lua_columnvector or lua_columnvector \stopluacode \def\columnvector#1{\ctxlua{document.matthias.lua_columnvector(#1)}} \starttext \startformula \columnvector{{1,2,3}} %% watch the double { ! \stopformula \stoptext -- luigi
