Cross multiplication --- Introduction ---

We all know that the multiplication of matrices is not commutative, that is, if A and B are two square matrices of the same size, the matrix C=AB-BA is not zero in general.
This exercise Cross multiplication therefore presents you two matrices, A and C, both of size . And your goal will be to find a matrix B such that AB-BA=C (or BA-AB=C, according to the circonstances).
