Shift a square matrix along a bigger square matrix by one

Let’s say I have a matrix,call it m2 with size of 4x4. I want to shift the matrix by one using for loop.

What do you mean by shift the matrix? Any example?

[John D'Errico]

Please give an example. Even the clarification comment you made is highly confusing.

Have a look at the help and documentation for the function circshift. That function should solve the problem you have described.

See either imfilter() or conv2().

If you're forced to do it manually, then there are many examples of sliding window filters on the forum.

You can use padarray for edge padding. See:
