Member Function Documentation

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