@ Chloe St John: it is not appreciated when you delete your question text. This has the effect of treating us as your own disposable personal assistants, which we are not. If you want private help then you will find plenty of consultants who will gladly take your money and offer whatever private advice you want.
If you are concerned about your tutor or professor finding that you have been given all answers to your homework, then perhaps consider that before posting onto a public forum:

Don't use a loop, learn to write simple vectorized code:
N = 5;
M = zeros(N);
M(1:N+1:end) = 1

n = zeros(5); %square matrix
for i= 1:size(n,1)
n(i,i) = 1;
end
