Create a matrix with one vector
显示 更早的评论
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)

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