Detailed Description

template<class M, class S>
class hdnum::DIRK< M, S >

Implementation of a general Diagonal Implicit Runge-Kutta method.

The ODE solver is parametrized by a model. The model also exports all relevant types for time and states. The ODE solver encapsulates the states needed for the computation.

Template Parameters

M	the model type
S	nonlinear solver

Constructor & Destructor Documentation

◆ DIRK() [1/2]

template<class M , class S >

hdnum::DIRK< M, S >::DIRK	(	const M &	model_,
		const S &	newton_,
		const ButcherTableau &	butcher_,
		const int	order_ )

inline

constructor stores reference to the model and requires a butcher tableau

◆ DIRK() [2/2]

template<class M , class S >

hdnum::DIRK< M, S >::DIRK	(	const M &	model_,
		const S &	newton_,
		const std::string	method )

inline

constructor stores reference to the model and sets the default butcher tableau corresponding to the given order
