Webbfor the matrix PA.Thus PA= LU, where L is lower triangular and U is upper triangular. We call this the PLU factorization. Let us summarize this in the following theorem. Theorem 7.1.1. Let A ∈M n (C). Then there is a permutation matrix P ∈M n (C) and lower L and upper U triangular matrices (∈M n (C)), such that PA= LU. WebbAdvanced Math questions and answers. a) prove that the product of two lower triangular matrices is a lower triangular matrix. b) Prove that the product of two unit lower triangular matrices is a unit lower triangular matrix. c)Prove that the inverse of a unit lower triangular matrix is a unit lower triangulatr matrix.
