在 MATLAB Online 中打开

for ii = 1:4
  subplot(2,2,ii);
  imshow(rand(200,300));
end

Different images for each subplot.

+1, I'd prefer image instead of imshow.

@Jan, why?

Other than for just preallicating an image into existence (i.e. image(1)); I've never really found much other use for image. imshow does all of the meta stuff that I expect with an image for free.
