Detailed Description

A functor like double (func) (double) const.

Member Function Documentation

operator()()

virtual double Gyoto::Functor::Double_Double_const::operator() ( double ) const

pure virtual

The actual function.

Implemented in Gyoto::Astrobj::PolishDoughnut::intersection_t, and Gyoto::Astrobj::PolishDoughnut::outerradius_t.

ridders()

double Gyoto::Functor::Double_Double_const::ridders	(	double	from,
		double	to ) const

Ridder's root-finding method applied on operator()().

Parameters

from,to

boundaries for root-searching

Returns

the root

secant()

double Gyoto::Functor::Double_Double_const::secant	(	double	from,
		double	to )

Secant root-finding method applied on operator()().

Sets status to -0 in case of convergence -1 if two distinct inputs evaluated to the same output -2 if maximum number of iterations (20) reached

Parameters

from,to

boundaries for root-finding

Returns

the root
