Do you mean similar numbers (as in within a certain threshold apart) or identical numbers? If identical, you can use the hist() function.
doc hist

Similar or identical? Those are different! .5 is similar to .6, but not identical.
If you mean identical, you can count how many times each number occurs like this:
A = randi(30,5,5)
N = unique(A(:));
N(:,2) = histc(A(:),N)
