Generating an example 3D array that has 10 slices
A = repmat([0 0 0 0; 1 0 0 0; 1 0 1 0],[1 1 10]);
Modifying the 4th & 8th slice to contain only zeros in rows and columns
A(:,:,4)=[0 0 0 0;0 0 0 0;0 0 0 0];
A(:,:,8)=[0 0 0 0;0 0 0 0;0 0 0 0];
Find the slice index in 3rd dimension that has only zeros in rows and columns
idx = all(A == 0, [1 2])
Now, delete the slices that has zeros from the original 3D array A
A(:,:,idx) = []
I hope this gives you an idea how to solve your problem.
