Offhand, I'm not aware of how to directly impose a monotonicity condition using B-splines. Of course, you could always choose a basis with fewer degrees of freedom than your number of sample points and then perform a least squares fit. You may still get some oscillations for oscillatory data, but they should be much slower ones. Tune as appropriate for your application. - Rhys _______________________________________________ Help-gsl mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-gsl
