ALL IN MATLAB

4. Implement function [L,U,P]=MakePLU (A) that implements LU decomposition with partial pivoting to compute LU = PA The algorithm should swap the row with the largest absolute value in the current column to the diagonal (you can only look at rows below the current one!). Test it with the matrices 5 6 0 and /01 2 3 -3 0 0 1 0 1 1/5 3 2 5 1 7/ Note: of course you may not use the existing lu(A) function
