How to create a 3D matrix from subtracting 2D matrices (like creating 2D matrix from subtracting vectors)?

I wish to extend the behavior of subtracting a row vector and a column vector to matrices. Let me provide an example: Suppose A and B are two n x n matrices. I want to obtain matrix C such that C(:,:,i) = A(:,i)-B(i,:), i runs from 1 to n.
Is there a way to do this without for-loops?
