The equivalent inverses are available (up to constant factors) via the cumulative distribution functions like gsl_cdf_gaussian_Pinv, etc for the gaussian distribution. I believe there's an open ticket on the bug tracker to move the implementation into the specfunc module and make it directly available as gsl_sf_erfinv. -- Brian Gough GNU Scientific Library - http://www.gnu.org/software/gsl/ _______________________________________________ Help-gsl mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-gsl
