Execute matrix in a "for loop"

I have matrix m that is (2000x5)(rowsxcolumns), and I have a code. I want to execute my code for each column of this matrix, i.e.

loop number #1 = m(2000,col1); #2 = m(2000,col2), ....... #5 = m(2000,col5). Does anybody know how to do that?

Let's say your function is foo, you can do

for ii = 1:size(m,2)
    y = foo(m(:,ii));
end
