Member Function Documentation

name()

const char* theplu::yat::utility::RootFinderDerivative::name ( void  ) const

inherited

Returns

name of the type of root finder

operator()() [1/2]

template<class FUNC >

double theplu::yat::utility::RootFinderDerivative::operator() ( FUNC &  func, double  guess, RootFinderDerivative::Stopper &&  stopper  )

inherited

Starting at guess, find a value x such that func(x) = 0. Function keeps iterating until stopper returns true.

Requirement on FUNC:

• double operator(x)
• double derivative(x)

operator()() [2/2]

template<class FUNC >

double theplu::yat::utility::RootFinderDerivative::operator() ( FUNC &  func, double  guess, RootFinderDerivative::Stopper &&  stopper, unsigned int  max_epochs  )

inherited

Same as operator()(4) but do maximum max_epochs iterations.
