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:
Mthe model type
Snonlinear solver

Constructor & Destructor Documentation

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

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
