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
easy
less easy
matrices,
A
and
C
, both of size
2×2
3×3
4×4
5×5
. And your goal will be to find a matrix
B
such that
AB-BA
=
C
(or
BA-AB
=
C
, according to the circonstances).
