Computes the factorization x = LU. This function is only defined for matrices and no pivoting is performed.
The function returns matrix z that contains the strictly lower triangular L without its unit diagonal, and the upper triangular U as submatrices. That is, if z = lufactorize(x), then z = U+L-E and x = LU. E is a unit matrix.
