We have to find LDU means lower diagonal upper triangular matrix so we will reduce it into echlon form and we can interchange the rows during the matrix operation.

1. (a) Factor the matrix into the form A= PT LU, where P is a permutation matrix: A = o 2 31 1 1 -1 . 10- 11 You may use the computer but each step of the factorization must be shown. In other words, this is to be done " by hand" but you can use the computer to do your basic arithmetic. (b) Determine the 2-norm of the matrix A using a built-in command on the computer.
