ROOT::Math::OneDimParamFunctionAdapter< ParamFuncType > Class Template Reference

template<class ParamFuncType = ROOT::Math::IParamMultiFunction &>
class ROOT::Math::OneDimParamFunctionAdapter< ParamFuncType >

OneDimParamFunctionAdapter class to wrap a multi-dim parametric function in one dimensional one.

Given a f(x[],p1,...pn) transforms in a f( p_i) given the param index i and the vectors x[] and p[] of the coordinates and parameters It has to be used carefully, since for efficiency reason it does not copy the parameter object but re-uses the given pointer for the p[] vector. The ParamFuncType reference by default is not const because the operator()(x,p) is not a const method
