Help making a matrix table

Could someone please help me make a matrix.

I need code that would make an NxN matrix with the pattern of:

if N=4

[1 1 1 1;

0 1 1 1;

0 0 1 1;

0 0 0 1]

Answer 1

[John D'Errico]

Can you create a matrix of all ones?

Consider the function triu. Read the help. Look at the examples.

Answer 2

Hi! Got your back, i'm leaving a code that can do that.

Also, you can consider making a ones matrix with 'ones(N)', and getting the upper triangular with 'triu(M)'.

Hope you find this useful! <3

% With 'N' as the dimention of a square matrix.
M = zeros(N);

for i = 1 : N
    for j = i : N
        M(i,j) = 1;
    end
end 

M = 3×3

1 1 1 0 1 1 0 0 1
