Hi
please always make "reply to all" and keep the mailing list CC'ed so
others can join in the discussion (specially if others have matlab and
cantest this for us).
OK. I'll do.

Can you explain this better. Do you mean to say that the function I
sent you last night is always working good, or that the previous
version had always been working good in other cases and my
modifications to it were too much?
Of course. I only asked that counts ([counts, x] = imhist(img);) array were
correct, and it works fine when I tested it. However, I cannot assure that
this function gives always the correct answer because I do not take care of
all the inputs, for example, imhist(X, map). In fact, imhist(img, n) does
not work when I test it with n = 2.

The histogram should only display if you ask for no output values (at
least that's what I understood from the MatLab documentation..
[counts,x]=imhist(img); ## no image, just output
imhist(img); ## no output, just image
In my computer, it does not display the image using the second sentence.
Greetings.
