GSL functions are regular C-functions and should be used as such. In your particular example, please, see GSL documentation, section 32 "One dimensional Root-Finding", subsection 32.10 "Examples" on how to pass functions as arguments to root solvers. By the way, implementation of your function could contain integrals, etc. Hope it helps, --Leo-- _______________________________________________ Help-gsl mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-gsl
