ROOT::Math::ParamFunction&	operator=(const ROOT::Math::ParamFunction&)
virtual const double*	Parameters() const
bool	ProvidesParameterGradient() const
virtual void	SetParameters(const double* p)

Data Members

protected:

vector<double>	fParGradient
vector<double>	fParams

private:

unsigned int	fNpar

Function documentation

virtual ~ParamFunction()

 destructor

{}

const double * Parameters()

 cloning

Deep copy of function (to be implemented by the derived classes)

virtual ParamFunction *  Clone() const = 0;

Access the parameter values

{ return &fParams.front(); }

void SetParameters(const double* p)

Set the parameter values
@param p vector of doubles containing the parameter values.

fParams = std::vector<double>(p,p+fNpar);

unsigned int NPar()

Return the number of parameters

{ return fNpar; }

bool ProvidesParameterGradient()

using BaseFunc::operator();

Return \a true if the calculation of derivatives is implemented

bool ProvidesGradient() const {  return fProvGrad; }

Return \a true if the calculation of derivatives with respect to the Parameters is implemented

{ return fProvParGrad; }
