T. Schütze.
Matlab programs for the computation of univariate and bivariate splines with free knots.
Due to several requests I decided to put my Matlab programs used in some of the papers above on the WWW. They come with little documentation and with no support. Use them as they are!
I would be pleased if you would inform me when you are using these programs in some applications.
