I have fitted a 2D Gaussian to a surface using the Lsqcurvefit. I need to get the probability density of the fit so I can compute the log-likelihood of the Gaussian model. The Matlab fitdist function seems to do this for vectors, but can it be used for getting the PD of a fitted surface and the matrix with the real values to be fitted? Are there other ways of getting the log-likelihood of the model?

Thanks for any help!

Based on my understanding you want to obtain the probabiliy distribution for the 2D data. The link attached below might help you:

Thanks, but the question is not answered in the link. I want to obtain the pdf of the fitted Gaussian given the matrix with the raw data.
