Hi all, I have made a new GSL extension library to aid in multi-dimensional least squares fits (ie: when your observations depend on more than one variable). It can be tricky to construct the least squares matrix X when you have 3 or higher dimensions in your model, so this extension is designed to make it very simple to construct the matrix.
It is located at: http://ucsu.colorado.edu/~alken/gsl/ndlinear-1.0.tar.gz and includes texi documentation in doc/ as well as an example program with plots of the results. I welcome any feedback. Brian - could you add a link for this to the GSL page? Patrick Alken
