@Mani Ahmadian: Hi Mani, thanks for your comment. I don't have a good method for dealing with outliers using variogramfit except using an optimization scheme other than "least squares". E.g., least absolute deviations may be less sensitive to outliers. In case you are supplying variogramfit with the binned, experimental variogram, I'd better care for outliers during binning. For example, you might want to adapt the function variogram ( http://www.mathworks.com/matlabcentral/fileexchange/20355-experimental--semi---variogram ) to compute the trimmed mean or median when aggregating binned variogram values.
