TeXForm parses this entry as prefix syntax; the package determines its argument specification.

\xmat{element}{rows}{cols} element & element & ... \\ element & element & ... (rows×cols grid)

Without star: repeats element literally. With star: adds subscript indices (single index for vectors, double indices for matrices).

\xmatrix{#1}{#2}{#3}exact
Same parser method and semantics for the unstarred form.
\xmatrix*{#1}{#2}{#3}exact
Same parser method and semantics for the starred form.
