[Help-gsl] gsl_function with pointer

[Ivan Liu]

Hi,

I hope to use to declare a gsl_function by pointer, and
use the integration rountine gsl_integration_qag in the
following way:


gsl_function * Integrand=0;
Integrand->function = &f;
Integrand->params = &list;

gsl_integration_qag (Integrand, x_start, x_end, epsabs, epsrel, limit, 1,
w, &resIntegral, &abserr);



it compiles successfully but fails on runtime.

is it not possible to declare gsl_function using pointer and pass it
to the gsl_integration_qag routine?

Regards,
Ivan Liu
