double	Root () const
	Returns the previously calculated root.

bool	SetFunction (const IGenFunction &f, double xlow, double xup)
	Sets the function for the rest of the algorithms.

virtual bool	SetFunction (const ROOT::Math::IGenFunction &, double, double)
	Sets the function for the rest of the algorithms.

virtual bool	SetFunction (const ROOT::Math::IGradFunction &, double)
	Sets the function for algorithms using derivatives.

bool	SetFunction (GSLFuncPointer f, void *params, double xlow, double xup)

bool	Solve (int maxIter=100, double absTol=1E-8, double relTol=1E-10)
	Find the root.

int	Status () const
	Return the status of last root finding.
