Sorry, I meant "imagesc".

If these functions return image handles, how do I use them with, say,
"imwrite"? The documentation for "imwrite" doesn't seem to have changed to
detail this. Now I just get "error: expecting integer index, found
-6.139061" when trying to use the results of "imagesc" with "imwrite".
