Detailed Description

double intersection(double) Functor class

Implement former double intersection(double) function as a Gyoto::Functor::Double_Double_const subclass to access generic root-finding methods.

This class is instantiated in a single PolishDoughnut::intersection member.

Member Function Documentation

operator()()

virtual double Gyoto::Astrobj::PolishDoughnut::intersection_t::operator() ( double ) const

virtual

The actual function.

Implements Gyoto::Functor::Double_Double_const.

ridders()

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

inherited

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 )

inherited

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
