Matrix-matrix division.
The following expression:
X = A / B
is equivalent to this one
X = A * pseudoInverse(B)
With the difference that the pseudoinverse matrix for B is not directly computed. Instead, the matrix equation:
X * B = A
is solved for the X term. This leads to more stable and efficient results than using the pseudo inverse.
this operator gets X from:
X = A / B -> X * B = A -> B' * X' = A'
using a linear system resolution based on a LU decomposition over A.
