Problem 1704. Triangular matrices in 3D array
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
