Hello Dear Experts,
Consider I have a non zero matrix A of size m x n.
I want to pad it with zeros on all sizes. What is the smartest way to pad it with p zero rows and q zero columns.
Thanks a lot in advance!

It's in the Image Processing Toolbox. Type ver on the command line to see if you are so unfortunate that you don't have it.
