i think the program u have given is a incomplete one.. it's also erroneous...it's trying to plot histograms for individual image plans r,g,b,...when I tried finishing the program and debug it...the loop is never ending ...giving the full program ..someone may be helpful to you..

If you are new with Matlab, the best thing to do is to read the getting started with Matlab. You can also learn what each function do by typing
help imhist
help size
and so on
