<static> CheckMatrix( [matrix])

Checks if an array can be used as a matrix.

A matrix is a two-dimensional array (array of arrays), where all sub-arrays (rows) have the same length. There must be at least two rows. This is an example matrix:

[

[ 2, 0, 0, 0, 0, 4 ],
[ 2, 0, 1, 2, 0, 4 ],
[ 2, 0, 3, 4, 0, 4 ],
[ 2, 0, 0, 0, 0, 4 ],
