Create a matrix with one vector

Hey,

I want to create a matrix out of one vector.

v=[1,2,3,4]

And the matrix should have the form

M= 1 2 3 4

2 2 3 4

3 3 3 4

4 4 4 4

Is there an easy solution for that?

Thanks

v=[1,2,3,4];

N = numel(v);
idx = max(1:N,(1:N).');
M = v(idx)

M = 4×4

1 2 3 4 2 2 3 4 3 3 3 4 4 4 4 4

v = [1,2,3,4];
max(v, v.')

ans = 4×4

1 2 3 4 2 2 3 4 3 3 3 4 4 4 4 4
