ROOT::Math::GSLFunctionWrapper Class Reference

Description

Wrapper class to the gsl_function C structure. This class to fill the GSL C structure gsl_function with the C++ function objcet. Use the class ROOT::Math::GSLFunctionAdapter to adapt the C++ function object to the right signature (function pointer type) requested by GSL
