It's a really useful work! But I have a question. This script will work only with subplots?

Because I tried with handles and I do not obtain what I wish:

load clown;
figure('position',[100 100 500 500]),

h1 = axes('position',[0.1 0.1 0.4 0.4]);
set(h1,'visible','on');
colormap('jet');
h1 = imagesc(X);
ext_freezeColors(h1);

h2 = axes('position',[0.6 0.1 0.4 0.4]);
set(h2,'visible','on');
colormap('gray');
h2 = imshow(mat2gray(X));
ext_freezeColors(h2);

The two images that I obtain are both gray:-(

Cool! Thanks!
