ROOT::Math::GSLMultiMinFunctionAdapter< UserFunc > Struct Template Reference

template<class UserFunc>
struct ROOT::Math::GSLMultiMinFunctionAdapter< UserFunc >


Class for adapting any multi-dimension C++ functor class to C function pointers used by GSL MultiMin algorithms.

The templated C++ function class must implement:

double operator( const double * x) and if the derivatives are required: void Gradient( const double * x, double * g)

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