Z = imabsdiff(X,Y) subtracts each element in array Y from the corresponding element in array X and returns the absolute difference in the corresponding element of the output array Z. If you passed two count arrays (histograms) in for X and Y, it would give the absolute value of the count differences, but what does that mean? Probably not what you hope it might. What are you trying to accomplish?
