[Help-gsl] Numerical quadrature performed on a set of points

[Hongzheng Wang]

Hi,

According to the manual of gsl, there are plenty of subroutines for
numerical quadrature provided by gsl.  But it seems that they are
performed on gsl_function objects which can generate necessary values
required by the undergone algorithm.  My question is, if the function
is known only on a set of points, how can the integration be
calculated conveniently?

Thanks.
