It already is an image. Any 2D array, or 3D for that matter, can be considered as an image. Why do you think your 2D array is not?

i meant, when i save 2d array in matlab ,as an image onto desktop and again read it back, my values are changing.

 I would like to know if i can save the array to an image without the, numbers above some particular value being converted to that particular value...Thanks in advance

h = image(uint16(YourArray));
fetched = get(h, 'CData');
%now see how much they differ
max(YourArray(:) - fetched(:))
