Jet function output error

I got a script that is to create a flux map using two images; image of reflected rays and image of the sun. The inital lines make sense and produce an output but the total result is null (the is no flux map) after running it. I realized the
jet (ceil (max(fmap_img(:)))
did not produce anything. Any help?

You must pass Jet an integer that is the number of colors it is supposed to create.
Try this:
numberOfColors = ceil (max(fmap_img(:))) % No semicolon
cmap = jet(numberOfColors) % Create a color map.
colormap(cmap); % Apply the colormap to the indexed/gray scale image.
What do you see in the command window? Does the image look pseudocolored now?
You might also want to look into caxis().

colormap(jet)
after the above code would produce that effect.
