operator()()

virtual double ROOT::Minuit2::GenericFunction::operator() ( const std::vector< double > &  x ) const

pure virtual

Evaluates the function using the vector containing the input values.

Parameters

x	vector of the coordinates (for example the x coordinate for a one-dimensional Gaussian)

Returns

the result of the evaluation of the function.

Implemented in ROOT::Minuit2::FumiliChi2FCN, ROOT::Minuit2::FumiliMaximumLikelihoodFCN, ROOT::Minuit2::FCNAdapter< Function >, ROOT::Minuit2::FumiliFCNAdapter< Function >, ROOT::Minuit2::FCNBase, ROOT::Minuit2::FCNGradAdapter< Function >, and ROOT::Minuit2::ParametricFunction.
