Modify the row elimination process so that it results in the lower diagonal matrix instead of the upper diagonal one.
ii) Determine the method to factorize any square matrix A into P A = UDL where P is permutation matrix, U is upper diagonal, D is diagonal and L is lower diagonal.
Determine:
i) half credit if method does not work but the reasoning is logical.
