G would be a colormap - a pseudocolor look up table for yout indexed image. You did not set it to anything before you called imshow(), so why did you put it in there.? Replace it with [] and see if that works for you.

You can use imshow(grayImage, [0 255]) if you want, or imshow(indexedImage, gray(256)) also. Or just define G yourself as a 256 by 3 array of numbers in the range 0-1, like
G = gray(256);
