Given a 3D numeric array x, return an array y of the same size in which all entries to the right of the main diagonal are zero for y(:,:,i).
Example
If
x(:,:,1) = 1 2 3
4 5 6
7 8 9
x(:,:,2) = 1 4 7
2 5 8
3 6 9
x(:,:,3) = 1 2 3
1 2 3
1 2 3
then
y(:,:,1) = 1 0 0
4 5 0
7 8 9
y(:,:,2) = 1 0 0
2 5 0
3 6 9
y(:,:,3) = 1 0 0
1 2 0
1 2 3
