Chapter 7, Problem 6(choose chapter or problem)
Let A = 547 2 4 3 286 , b = 2 5 4 , c = 5 4 2 (a) Use complete pivoting to solve the system Ax = b. (b) Let P be the permutation matrix determined by the pivot rows, and let Q be the permutation matrix determined by the pivot columns. Factor PAQ into a product LU. (c) Use the LU factorization from part (b) to solve the system Ax = c
