I need Matlab Help

Uslng MATLAB Create a function LU-factorization that performs the LU factorization of a matrix A. You may use the previous functions you implemented. The function header should at least contain function [L, U] LU-factorization (A) = Create a function forward-substitution that solve the system Ly = b, when L is a lower trian- gular matrix. The function header should look something like function y-forward substitution (L, b) Let us recall that the output has to be a vector Use those two functions and the function backward substitution to solve (1). Do you find the same solution? Call, L, U, y, x the results. compare your solution to x0 obtained with the Matlab command A\b. Call Err the absolute error. Comment using %.
