Problem using functions output

working with some simple functions there are times when the values are displayed and times when they are not, is it something i am doing wrong or might it be matlab. It is probably myself but i don't see it. Here are two sample functions, Even with the ; sometimes output values are shown.

function [AI,dm,AIrows,AIcols] = image_stats(f)
dm = size(f);
AI = mean2(f);
AIrows = mean(f, 2);
AIcols = mean(f, 1);

end

function s = image_struct_loop(f)
K = size(f);
for k = 1:K(3)
s(k).dim = size(f(:, :, k));
s(k).AI = mean2(f(:, :, k));
s(k).Alrows = mean(f(:,:, k), 2);
s(k).Alcols = mean(f(:, :, k), 1);
end
end

I don't see anything in the code that would display anything. You have semicolons after every line to suppress output to the command window, you have no fprintf(), no disp(), no echo, no msgbox(), no helpdlg(), no warndlg(), or any other kind of way to display something. Tell me exactly what gets displayed, and where it gets displayed.
