Name       Size            Bytes  Class     Attributes
gb        71x71            40328  double
>> ndims gb
ans =
     2
description about img_out
img_out = zeros(size(img_in,1), size(img_in,2), N); where N = 12
whos img_out Name Size Bytes Class Attributes
img_out      3x3x2              144  double
