Great I can now show images. However, the images doesn't appear to be 
correctly shown. If I type "imshow(rand(100))" I should see a gray-scale 
image of random colors, but I see a color image.

I'm not sure anything needs fixing, I just found it to be odd that you 
have drawnow inside the drawing functions and also call it before the 
user gets control of the prompt. Seems like you do the same thing twice 
then.
