That's a typedef, not a function. You can see in qag.c and qagp.c where the typedef is used to get a function pointer to a particular integration rule (e.g. gsl_integration_qk15 in qag.c). I believe many of the concrete rules listed in gsl_integration.h fit that signature. - Rhys _______________________________________________ Help-gsl mailing list Help-gsl@gnu.org https://lists.gnu.org/mailman/listinfo/help-gsl
