Then, create a slider within the panel by calling the uicontrol function with the panel specified as the parent and 'Style' specified as 'slider'. So now you can take different images with different light conditions, equalize it and check the results. this histogram to either ends (as given in below image, from Wikipedia) and that is what Histogram Equalization does (in simple region as we saw in previous cases.
