PYTHON -LU factorization 

(please see attached image for full question)
.

Program (in a Python function) a LU factorization algorithm (without using
(mxm)
pivoting) for a matrix A. The factorization is obtained by elimination steps
k=1,...,m- 1 so that
V
i=k+1,...,m and j=k,...,m
where the multipliers mi,k are given by mi, k =
When k = m - 1, Am), , is upper
triangular, that is,U₁,j = A). The lower triangular matrix is obtained using the
multipliers mi,k, that is Lij = mij V i > j, Li,i = 1, and Lij =ij.
