ROOT::Math::GSLMultiFitFunctionAdapter< FuncVector > Class Template Reference

template<class FuncVector>
class ROOT::Math::GSLMultiFitFunctionAdapter< FuncVector >

Class for adapting a C++ functor class to C function pointers used by GSL MultiFit Algorithm 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) and void FdF( const double * x, double &f, 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
