MATLAB: How to create a colorbar for the subplots and associate the colorbar with the figure rather than each individual axes in MATLAB 7.7 (R2008b)

Below is an example that demonstrates how to create a colorbar for your subplots, and associate the colorbar with the figure rather than each individual axes. Note that the position of each of the axes needs to be altered.

ax(1)=subplot(4,1,1);
imagesc(magic(5),[1 64])
ax(2)=subplot(4,1,2);
imagesc(magic(6),[1 64])
ax(3)=subplot(4,1,3);
imagesc(magic(7),[1 64])
ax(4)=subplot(4,1,4);
imagesc(magic(8),[1 64])
h=colorbar;
set(h, 'Position', [.8314 .11 .0581 .8150])
for i=1:4
      pos=get(ax(i), 'Position');
      set(ax(i), 'Position', [pos(1) pos(2) 0.85*pos(3) pos(4)]);
end
