Question

2.6 #11 The Problem is about Elimination = Factorization: A= LU from Linear Algebra

Please, solve computing the factorization A = LU (and also A = LDU).

I WILL NOT RATE SOLUTIONS THAT USE REDUCTION BY ECHELON RULE or other more advanced method!

What are L and D (the diagonal pivot matrix) for this matrix A? What is U in A = LU and what is the new U in A = LDU?

A is a 3×3 matrix with rows: (2 4 8), (0 3 9), and (0 0 7).
The matrix is already triangular.
