Question

What is wrong with this code to perform LU decomposition in matlab?

function [L,U] = LUDecomp(A)

dim = size(A);
n = dim(1);
m = dim(2);

if n~=m
error('Matrix A is not a square')
end

L = eye(n);
U = A;

for i = 1:n
for j = 1:m
alpha = U(i,i);
U(i,:) = -alpha*U(j,:);
L(i,j) = alpha*L(i,j);
end
end
