MATLAB How to divide a matrix into equals parts?

Question

Let's say I have a 100x100 matrix, I want to divide it into equals parts of 10x10.

The problem is that the input matrix can be of any size but always mod 10. I looked at the mat2cell function but it does not seem to work for a dynamic number of parts. Or am I missing something?

Thanks!

Answer 1

You just have to tell mat2cell exactly how you want the matrix divided up. If you're positive that it is always going to be a multiple of 10 in both directions, then it is (fairly) simple. Assuming that X is the matrix that you want to divide, and you want the resulting cell array in Y:

Y = mat2cell(X, repmat(10,[1 size(X,1)/10]), repmat(10,[1 size(X,2)/10]));
