Hello,
This macro that is not mine worked very well. I just tested the following

Otared has already answered your question but ...
\math{M^3=\startpmatrix
\NC 2 \NC 3 \NC 6 \NC 4 \NC 2 \NC 7 \NC 3 \NC 1 \NR
\NC 3 \NC 0 \NC 1 \NC 1 \NC 2 \NC 3 \NC 6 \NC 4 \NR
\NC 6 \NC 1 \NC 4 \NC 4 \NC 4 \NC 9 \NC 10 \NC 6 \NR
\NC 4 \NC 1 \NC 4 \NC 4 \NC 5 \NC 8 \NC 8 \NC 3 \NR

\stoppmatrix}
If you type a lot of such matrices, you might find the attached module interesting. Using it you can use matlab-like syntax for writing matrices:
\usemodule[simplematrix]
\definesimplematrix[MATRIX][fence=parenthesis, align=middle]
\starttext
$\MATRIX{1,2,3,4;5,6,7,8;9,10,11,12}$
\stoptext
