5x5 grid of black squares

I'm trying to lot a 5x5 grid of black boxes. I know i have to use a loop and but having trouble filling the boxes and get the printed on a figure. The code i have so far is:

for i = 1:25
    handles = zeros(25,1);
    x=mod(i,5);
y=floor(1/5);

    handles(i) = fill(x,y, 5,5,'k');


end

I am not certain what you want.

Try this:

blksqrx = [0 1 1 0];
blksqry = [0 0 1 1];

figure
hold all
for k1 = 1:5
    for k2 = 1:5
        patch(blksqrx+(k1-1)*1.1, blksqry+(k2-1)*1.1, 'k')
    end
end
hold off
axis tight

This separates them. If you want them to be contiguous, use this patch call instead:

patch(blksqrx+(k1-1), blksqry+(k2-1), 'k')

Experiment to get the result you want.

I have written pseudocode of what i am wanting to do but can't seem to figure out the "handles(i)= fil()" to make a 5x5 grid of black boxes

You can get the handles to each patch object easily enough.

Substitute this line for my original patch call:

h((k1-1)*5+k2) = patch(blksqrx+(k1-1)*1.1, blksqry+(k2-1)*1.1, 'k');

That will give you all 25 of them.
