I have a macro to typeset function definitions:
\define[5]\functionarray
{
\startalign[n=4, align={left,right,center,left}]
\NC #1: \NC #2 \NC \to \NC #3 \NR
\NC \NC #4 \NC \mapsto \NC #5
\stopalign
}
I use it like this: (notice the period at the end)
\startformula
\functionarray{f}{X}{Y}{x}{f(x)}.
\stopformula
I get the following error:
Display math should end with \Ustopdisplaymath ...
If I remove the ".", the error does not happen.
How should I implement my "functionarray"?
Use mathmatrix.
\definemathmatrix[functionarray][n=4, align={left,right,middle,left},
distance=0.2em]
\define[5]\functionarray
{\startfunctionarray
\NC #1: \NC #2 \NC \to \NC #3 \NR
\NC \NC #4 \NC \mapsto \NC #5 \NR
\stopfunctionarray}
