imshow() assumes that arrays of type single() or double() are in the range 0 to 1. Your arrays are not in that range. You should use imshow(TheArrayName, []) if you want the maximum value in the array to match to the last color in your color map and you want the minimum value in the array to match to the first color in your color map.
