-% RES = ZCONV2(MTX1, MTX2, CTR)
-%
-% Convolution of two matrices, with boundaries handled as if the larger mtx
-% lies in a sea of zeros. Result will be of size of LARGER vector.
-% 
-% The origin of the smaller matrix is assumed to be its center.
-% For even dimensions, the origin is determined by the CTR (optional) 
-% argument:
-%      CTR   origin
-%       0     DIM/2      (default)
-%       1     (DIM/2)+1  (behaves like conv2(mtx1,mtx2,'same'))
