Question: 5 the process of determining the lu factorization using only...

Question details

5. The process of determining the LU factorization using only elementary matrices obtained from row replacenient is sometimes not possible such as the case of A = 1 2 4 | from (3). There is no way to add multiples of row one to rows two and three so as to obtain A2,-A3,-0. To remedy this problem, we finst swap two rows of A in the process of constructing U. Let A 2 4and suppose Pis the permutation matrix obtained in (3) 01 3
