I have a 2D data, xy plane is my pixels and z axis is the values corresponding to each pixel(like an image).
I want to model my z data with Gaussians, how can I cluster my data and fit multi peak Gaussians?
Is there such a package of Matlab or any other way, code etc.?

Thanks a lot

Are your Gaussians well separated, or are they mixed? If they're well
separated, you can use the CLEAN algorithm used in astronomy to find
stars:

I've talked about it before - explained the algorithm. Search the
newsgroup for my earlier messages.
