It doesn't appear that you're willing enough to put in enough time to clearly state what you want, so I doubt anyone will put in more time than you have in solving your problem for you. By the way, what was wrong with using the hist function to inspect your distribution?

Actually I have to vary sigma which appear in Gaussian. so i can use hist or histc. density distribution which should be Gaussian. and I check density is a 2d matrix. can you please explain me if its enough information.

Not really. Take a deep breath, let it out, and start explaining from the beginning. Assume that you're explaining the problem to someone who has absolutely no idea about the nature of the problem you're trying to solve (which is actually a pretty valid assumption in this case.) Don't worry too much about writing too much unless your message starts looking like a scholarly paper you could submit to a journal. If you have a small (emphasis on SMALL) example that demonstrates what you're trying to do, that would be good to include as well. -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ
