imshow() does not take any matrix, the values mast be of some format (i am not sure). You can use imagesc(), which, I think, can take pretty much anything. If you want your image to be grayscale, do colormap('gray')

Answer 2

[Walter Roberson]

Are you running in Mac OS Lion, and is using imshow crashing MATLAB?

If so could you double check to see whether you are perhaps running R2009A or earlier? R2009A or earlier together with Lion is has a known problem with imshow()

Note that if you use -nojvm then you will probably not be able to display any graphics include using imshow()
