how to subplot different size

I want to compare results but the results are all the same, how do I differentiate?

Try

subplot(2, 2, k); % k is 1, 2, 3, or 4
g = gcf;
g.WindowState = 'maximized';

to make it a 2 by 2 array of images and maximized on your screen.

You might also look at the "truesize" function, or see my attached zoom demo.

Also keep in mind that the third input to subplot can be a vector as long as they refer to a rectangular set of subplots.

subplot(3, 3, 1:3, 'Color', 'r') % top row of the 3x3 grid
subplot(3, 3, [4 7], 'Color', 'b') % bottom 2/3 of the first column of the grid
ax = subplot(3, 3, [5 6 8 9]); % the rest of the grid
plot(ax, 1:10, 1:10)

For images like these, you can also use montage:

>> montage({img1,img2, img3,....})
