I couldn't find it, but maybe with more browsing, you can:

I never heard of it. Presumably you know what it is so can't you just start writing?

[ali elshaar]

thanks for your reply ...its an efficient algorithm for contrast enhancement depends on grouping the histogram components of a low-contrast image into a proper number of groups according to a certain criterion,then redistribute these groups of histogram components uniformly over the grayscale so that each group occupies a grayscale segment of the same size as the other groups, and finally ungroup the previously grouped gray-levels

 the paper i talked about is(Gray-Level Grouping (GLG): An Automatic Method
for Optimized Image Contrast Enhancement—Part I:
The Basic Method)

No wonder I haven't heard of it. It's some name that the authors of one paper invented. So code it up and let us know if you have error messages. We're not going to code it up for you. You can do that as well as we can, and who better to do it than you? http://matlab.wikia.com/wiki/FAQ#Can_you_program_up_the_algorithm_in_this_article_for_me_and_explain_it_to_me.3F

i asked if the code of this algorithm is available in the internet or not as i will fused this with anther algorithm ..... can you help me downloading its code from this site please as i have no acess to it

I don't have an account on that site like it requires, and I don't want to get one just for this. Why can't you get your own account and download it yourself?
