Error in an image

What code do I need in order to find out:

How to check that one image is larger than another image (both rows and columns).

AND

Check that both images are viewable images (three-dimensional, three-layered matrices).

AND

If either of these conditions are not met, produce an error and terminate the program.

Answer 1

[Walter Roberson]

ndims(First_Image) == 3 && ndims(Second_Image) == 3 && size(First_Image,[1 2]) >= size(Second_Image, [1 2]) && size(First_Image,3) == 3 && size(Second_Image,3) == 3

This can be written more clearly.

Note: size(First_Image,[1 2]) requires a pretty new MATLAB.
