Details:

Here is an implementation of a missing function imapplymatrix. MATLAB docs:
https://www.mathworks.com/help/images/ref/imapplymatrix.html

I do some reshaping of X first in order to perform a vectorized multiplication
with M and then similar reshaping back the output size, reshaping four times.
It is not an optimal algorithm but it works.
