MATLAB: How to append a row average to a new matrix

arraycell arraysmatrix array

I have a 500×500 size matrix and I am trying to get the average of every 5 values in a row to make it a 100×100 matrix. How do I do that?
foo = randi(500,500)

Best Answer

With a little bit of guessing. Does this answer your question?
%%
foo = randi(500,500);
cac = mat2cell( foo, 5*ones(100,1), 5*ones(100,1) );
num = cellfun( @(sub) mean(sub(:)), cac );
num is <100x100>
