ROOT::Math::GSLFunctionAdapter< UserFunc > Class Template Reference

Description

template<class UserFunc>
class ROOT::Math::GSLFunctionAdapter< UserFunc >

Class for adapting any C++ functor class to C function pointers used by GSL. The templated C++ function class must implement:

double operator( double x) and if the derivatives are required: double Gradient( double x)

This class defines static methods with will be used to fill the gsl_function and gsl_function_fdf structs used by GSL. See for examples the GSL online manual
