* \brief Integrates the ODE with constant step size.

*
|

* This function is similar to integrate_const. The observer is called at

* equidistant time intervals t0 + n*dt.
|
||||
* If the Stepper is a normal stepper without step size control, dt is also
|
||||
* used for the numerical scheme. If a ControlledStepper is provided, the
|
||||
* algorithm might reduce the step size to meet the error bounds, but it is
|
||||
* ensured that the observer is always called at equidistant time points
|
||||
* t0 + n*dt. If a DenseOutputStepper is used, the step size also may vary
|
||||
* and the dense output is used to call the observer at equidistant time
|
||||
* points. The final integration time is always t0 + num_of_steps*dt.
|

*
|
||||
* \param stepper The stepper to be used for numerical integration.
|
||||
* \param system Function/Functor defining the rhs of the ODE.
|

* \class explicit_error_stepper_base
|
||||
* \brief Base class for explicit steppers with error estimation. This class can used with
|
||||
* controlled steppers for step size control.
|
||||
*
|
||||
* This class serves as the base class for all explicit steppers with algebra and operations. In contrast to
|
||||
* explicit_stepper_base it also estimates the error and can be used in a controlled stepper to provide
|
||||
* step size control.
|
||||
*
|
||||
* \note This stepper provides `do_step` methods with and without error estimation. It has therefore three orders,
|
||||
* one for the order of a step if the error is not estimated. The other two orders are the orders of the step and
|
||||
* the error step if the error estimation is performed.
|
||||
*
|
||||
* explicit_error_stepper_base is used as the interface in a CRTP (currently recurring template
|
||||
* pattern). In order to work correctly the parent class needs to have a method
|
||||
* `do_step_impl( system , in , dxdt_in , t , out , dt , xerr )`.
|
||||
* explicit_error_stepper_base derives from algebra_stepper_base.
|
||||
*
|
||||
* explicit_error_stepper_base provides several overloaded `do_step` methods, see the list below. Only two of them
|
||||
* are needed to fulfill the Error Stepper concept. The other ones are for convenience and for performance. Some
|
||||
* of them simply update the state out-of-place, while other expect that the first derivative at `t` is passed to the
|
||||
* stepper.
|
||||
*
|
||||
* - `do_step( sys , x , t , dt )` - The classical `do_step` method needed to fulfill the Error Stepper concept. The
|
||||
* state is updated in-place. A type modelling a Boost.Range can be used for x.
|
||||
* - `do_step( sys , x , dxdt , t , dt )` - This method updates the state in-place, but the derivative at the point `t`
|
||||
* must be explicitly passed in `dxdt`.
|
||||
* - `do_step( sys , in , t , out , dt )` - This method updates the state out-of-place, hence the result of the step
|
||||
* is stored in `out`.
|
||||
* - `do_step( sys , in , dxdt , t , out , dt )` - This method update the state out-of-place and expects that the
|
||||
* derivative at the point `t` is explicitly passed in `dxdt`. It is a combination of the two `do_step` methods
|
||||
* above.
|
||||
* - `do_step( sys , x , t , dt , xerr )` - This `do_step` method is needed to fulfill the Error Stepper concept. The
|
||||
* state is updated in-place and an error estimate is calculated. A type modelling a Boost.Range can be used for x.
|
||||
* - `do_step( sys , x , dxdt , t , dt , xerr )` - This method updates the state in-place, but the derivative at the
|
||||
* point `t` must be passed in `dxdt`. An error estimate is calculated.
|
||||
* - `do_step( sys , in , t , out , dt , xerr )` - This method updates the state out-of-place and estimates the error
|
||||
* during the step.
|
||||
* - `do_step( sys , in , dxdt , t , out , dt , xerr )` - This methods updates the state out-of-place and estimates
|
||||
* the error during the step. Furthermore, the derivative at `t` must be passed in `dxdt`.
|
||||
*
|
||||
* \note The system is always passed as value, which might result in poor performance if it contains data. In this
|
||||
* case it can be used with `boost::ref` or `std::ref`, for example `stepper.do_step( boost::ref( sys ) , x , t , dt );`
|
||||
*
|
||||
* \note The time `t` is not advanced by the stepper. This has to done manually, or by the appropriate `integrate`
|
||||
* routines or `iterator`s.
|
||||
*
|
||||
* \tparam Stepper The stepper on which this class should work. It is used via CRTP, hence explicit_stepper_base
|
||||
* provides the interface for the Stepper.
|
||||
* \tparam Order The order of a stepper if the stepper is used without error estimation.
|
||||
* \tparam StepperOrder The order of a step if the stepper is used with error estimation. Usually Order and StepperOrder have
|
||||
* the same value.
|
||||
* \tparam ErrorOrder The order of the error step if the stepper is used with error estimation.
|
||||
* \tparam State The state type for the stepper.
|
||||
* \tparam Value The value type for the stepper. This should be a floating point type, like float,
|
||||
* double, or a multiprecision type. It must not necessary be the value_type of the State. For example
|
||||
* the State can be a `vector< complex< double > >` in this case the Value must be double.
|
||||
* The default value is double.
|
||||
* \tparam Deriv The type representing time derivatives of the state type. It is usually the same type as the
|
||||
* state type, only if used with Boost.Units both types differ.
|
||||
* \tparam Time The type representing the time. Usually the same type as the value type. When Boost.Units is
|
||||
* used, this type has usually a unit.
|
||||
* \tparam Algebra The algebra type which must fulfill the Algebra Concept.
|
||||
* \tparam Operations The type for the operations which must fulfill the Operations Concept.
|
||||
* \tparam Resizer The resizer policy class.

* \class explicit_error_stepper_fsal_base
|
||||
* \brief Base class for explicit steppers with error estimation and stepper fulfilling the FSAL (first-same-as-last)
|
||||
* property. This class can be used with controlled steppers for step size control.
|
||||
*
|
||||
* This class serves as the base class for all explicit steppers with algebra and operations and which fulfill the FSAL
|
||||
* property. In contrast to explicit_stepper_base it also estimates the error and can be used in a controlled stepper
|
||||
* to provide step size control.
|
||||
*
|
||||
* The FSAL property means that the derivative of the system at t+dt is already used in the current step going from
|
||||
* t to t +dt. Therefore, some more do_steps method can be introduced and the controlled steppers can explicitly make use
|
||||
* of this property.
|
||||
*
|
||||
* \note This stepper provides `do_step` methods with and without error estimation. It has therefore three orders,
|
||||
* one for the order of a step if the error is not estimated. The other two orders are the orders of the step and
|
||||
* the error step if the error estimation is performed.
|
||||
*
|
||||
* explicit_error_stepper_fsal_base is used as the interface in a CRTP (currently recurring template
|
||||
* pattern). In order to work correctly the parent class needs to have a method
|
||||
* `do_step_impl( system , in , dxdt_in , t , out , dxdt_out , dt , xerr )`.
|
||||
* explicit_error_stepper_fsal_base derives from algebra_stepper_base.
|
||||
*
|
||||
* This class can have an intrinsic state depending on the explicit usage of the `do_step` method. This means that some
|
||||
* `do_step` methods are expected to be called in order. For example the `do_step( sys , x , t , dt , xerr )` will keep track
|
||||
* of the derivative of `x` which is the internal state. The first call of this method is recognized such that one
|
||||
* does not explicitly initialize the internal state, so it is safe to use this method like
|
||||
*
|
||||
* \code
|
||||
* stepper_type stepper;
|
||||
* stepper.do_step( sys , x , t , dt , xerr );
|
||||
* stepper.do_step( sys , x , t , dt , xerr );
|
||||
* stepper.do_step( sys , x , t , dt , xerr );
|
||||
* \endcode
|
||||
*
|
||||
* But it is unsafe to call this method with different system functions after each other. Do do so, one must initialize the
|
||||
* internal state with the `initialize` method or reset the internal state with the `reset` method.
|
||||
*
|
||||
* explicit_error_stepper_fsal_base provides several overloaded `do_step` methods, see the list below. Only two of them are needed
|
||||
* to fulfill the Error Stepper concept. The other ones are for convenience and for better performance. Some of them
|
||||
* simply update the state out-of-place, while other expect that the first derivative at `t` is passed to the stepper.
|
||||
*
|
||||
* - `do_step( sys , x , t , dt )` - The classical `do_step` method needed to fulfill the Error Stepper concept. The
|
||||
* state is updated in-place. A type modelling a Boost.Range can be used for x.
|
||||
* - `do_step( sys , x , dxdt , t , dt )` - This method updates the state x and the derivative dxdt in-place. It is expected
|
||||
* that dxdt has the value of the derivative of x at time t.
|
||||
* - `do_step( sys , in , t , out , dt )` - This method updates the state out-of-place, hence the result of the step
|
||||
* is stored in `out`.
|
||||
* - `do_step( sys , in , dxdt_in , t , out , dxdt_out , dt )` - This method updates the state and the derivative
|
||||
* out-of-place. It expects that the derivative at the point `t` is explicitly passed in `dxdt_in`.
|
||||
* - `do_step( sys , x , t , dt , xerr )` - This `do_step` method is needed to fulfill the Error Stepper concept. The
|
||||
* state is updated in-place and an error estimate is calculated. A type modelling a Boost.Range can be used for x.
|
||||
* - `do_step( sys , x , dxdt , t , dt , xerr )` - This method updates the state and the derivative in-place. It is assumed
|
||||
* that the dxdt has the value of the derivative of x at time t. An error estimate is calculated.
|
||||
* - `do_step( sys , in , t , out , dt , xerr )` - This method updates the state out-of-place and estimates the error
|
||||
* during the step.
|
||||
* - `do_step( sys , in , dxdt_in , t , out , dxdt_out , dt , xerr )` - This methods updates the state and the derivative
|
||||
* out-of-place and estimates the error during the step. It is assumed the dxdt_in is derivative of in at time t.
|
||||
*
|
||||
* \note The system is always passed as value, which might result in poor performance if it contains data. In this
|
||||
* case it can be used with `boost::ref` or `std::ref`, for example `stepper.do_step( boost::ref( sys ) , x , t , dt );`
|
||||
*
|
||||
* \note The time `t` is not advanced by the stepper. This has to done manually, or by the appropriate `integrate`
|
||||
* routines or `iterator`s.
|
||||
*
|
||||
* \tparam Stepper The stepper on which this class should work. It is used via CRTP, hence explicit_stepper_base
|
||||
* provides the interface for the Stepper.
|
||||
* \tparam Order The order of a stepper if the stepper is used without error estimation.
|
||||
* \tparam StepperOrder The order of a step if the stepper is used with error estimation. Usually Order and StepperOrder have
|
||||
* the same value.
|
||||
* \tparam ErrorOrder The order of the error step if the stepper is used with error estimation.
|
||||
* \tparam State The state type for the stepper.
|
||||
* \tparam Value The value type for the stepper. This should be a floating point type, like float,
|
||||
* double, or a multiprecision type. It must not necessary be the value_type of the State. For example
|
||||
* the State can be a `vector< complex< double > >` in this case the Value must be double.
|
||||
* The default value is double.
|
||||
* \tparam Deriv The type representing time derivatives of the state type. It is usually the same type as the
|
||||
* state type, only if used with Boost.Units both types differ.
|
||||
* \tparam Time The type representing the time. Usually the same type as the value type. When Boost.Units is
|
||||
* used, this type has usually a unit.
|
||||
* \tparam Algebra The algebra type which must fulfill the Algebra Concept.
|
||||
* \tparam Operations The type for the operations which must fulfill the Operations Concept.
|
||||
* \tparam Resizer The resizer policy class.

* \class explicit_stepper_base
|
||||
* \brief Base class for explicit steppers without step size control and without dense output.
|
||||
*
|
||||
* This class serves as the base class for all explicit steppers with algebra and operations.
|
||||
* Step size control and error estimation as well as dense output are not provided. explicit_stepper_base
|
||||
* is used as the interface in a CRTP (currently recurring template pattern). In order to work
|
||||
* correctly the parent class needs to have a method `do_step_impl( system , in , dxdt_in , t , out , dt )`.
|
||||
* This is method is used by explicit_stepper_base. explicit_stepper_base derives from
|
||||
* algebra_stepper_base. An example how this class can be used is
|
||||
*
|
||||
* \code
|
||||
* template< class State , class Value , class Deriv , class Time , class Algebra , class Operations , class Resizer >
|
||||
* class custom_euler : public explicit_stepper_base< 1 , State , Value , Deriv , Time , Algebra , Operations , Resizer >
|
||||
* {
|
||||
* public:
|
||||
*
|
||||
* typedef explicit_stepper_base< 1 , State , Value , Deriv , Time , Algebra , Operations , Resizer > base_type;
|
||||
*
|
||||
* custom_euler( const Algebra &algebra = Algebra() ) { }
|
||||
*
|
||||
* template< class Sys , class StateIn , class DerivIn , class StateOut >
|
||||
* void do_step_impl( Sys sys , const StateIn &in , const DerivIn &dxdt , Time t , StateOut &out , Time dt )
|
||||
* {
|
||||
* m_algebra.for_each3( out , in , dxdt , Operations::scale_sum2< Value , Time >( 1.0 , dt );
|
||||
* }
|
||||
*
|
||||
* template< class State >
|
||||
* void adjust_size( const State &x )
|
||||
* {
|
||||
* base_type::adjust_size( x );
|
||||
* }
|
||||
* };
|
||||
* \endcode
|
||||
*
|
||||
* For the Stepper concept only the `do_step( sys , x , t , dt )` needs to be implemented. But this class
|
||||
* provides additional `do_step` variants since the stepper is explicit. These methods can be used to increase
|
||||
* the performance in some situation, for example if one needs to analyze `dxdt` during each step. In this case
|
||||
* one can use
|
||||
*
|
||||
* \code
|

|
||||
* stepper.do_step( sys , x , dxdt , t , dt ); // the value of dxdt is used here
|
||||
* t += dt;
|
||||
* \endcode
|
||||
*
|
||||
* In detail explicit_stepper_base provides the following `do_step` variants
|
||||
* - `do_step( sys , x , t , dt )` - The classical `do_step` method needed to fulfill the Stepper concept. The state is updated in-place.
|
||||
* A type modelling a Boost.Range can be used for x.
|
||||
* - `do_step( sys , in , t , out , dt )` - This method updates the state out-of-place, hence the result of the step is stored in `out`.
|
||||
* - `do_step( sys , x , dxdt , t , dt )` - This method updates the state in-place, but the derivative at the point `t` must be
|
||||
* explicitly passed in `dxdt`. For an example see the code snippet above.
|
||||
* - `do_step( sys , in , dxdt , t , out , dt )` - This method update the state out-of-place and expects that the derivative at the point
|
||||
* `t` is explicitly passed in `dxdt`. It is a combination of the two `do_step` methods above.
|
||||
*
|
||||
* \note The system is always passed as value, which might result in poor performance if it contains data. In this case it can be used with `boost::ref`
|
||||
* or `std::ref`, for example `stepper.do_step( boost::ref( sys ) , x , t , dt );`
|
||||
*
|
||||
* \note The time `t` is not advanced by the stepper. This has to done manually, or by the appropriate `integrate` routines or `iterator`s.
|
||||
*
|
||||
* \tparam Stepper The stepper on which this class should work. It is used via CRTP, hence explicit_stepper_base
|
||||
* provides the interface for the Stepper.
|
||||
* \tparam Order The order of the stepper.
|
||||
* \tparam State The state type for the stepper.
|
||||
* \tparam Value The value type for the stepper. This should be a floating point type, like float,
|
||||
* double, or a multiprecision type. It must not necessary be the value_type of the State. For example
|
||||
* the State can be a `vector< complex< double > >` in this case the Value must be double.
|
||||
* The default value is double.
|
||||
* \tparam Deriv The type representing time derivatives of the state type. It is usually the same type as the
|
||||
* state type, only if used with Boost.Units both types differ.
|
||||
* \tparam Time The type representing the time. Usually the same type as the value type. When Boost.Units is
|
||||
* used, this type has usually a unit.
|
||||
* \tparam Algebra The algebra type which must fulfill the Algebra Concept.
|
||||
* \tparam Operations The type for the operations which must fulfill the Operations Concept.
|
||||
* \tparam Resizer The resizer policy class.

* \class symplectic_nystroem_stepper_base
|
||||
* \brief Base class for all symplectic steppers of Nystroem type.
|
||||
*
|
||||
* This class is the base class for the symplectic Runge-Kutta-Nystroem steppers. Symplectic steppers are usually
|
||||
* used to solve Hamiltonian systems and they conserve the phase space volume, see
|
||||
* <a href="http://en.wikipedia.org/wiki/Symplectic_integrator">en.wikipedia.org/wiki/Symplectic_integrator</a>.
|
||||
* Furthermore, the energy is conserved
|
||||
* in average. In detail this class of steppers can be used to solve separable Hamiltonian systems which can be written
|
||||
* in the form H(q,p) = H1(p) + H2(q). q is usually called the coordinate, while p is the momentum. The equations of motion
|
||||
* are dq/dt = dH1/dp, dp/dt = -dH2/dq.
|
||||
*
|
||||
* ToDo : add formula for solver and explanation of the coefficients
|
||||
*
|
||||
* symplectic_nystroem_stepper_base uses odeints algebra and operation system. Step size and error estimation are not
|
||||
* provided for this class of solvers. It derives from algebra_stepper_base. Several `do_step` variants are provided:
|
||||
*
|
||||
* - `do_step( sys , x , t , dt )` - The classical `do_step` method. The sys can be either a pair of function objects
|
||||
* for the coordinate or the momentum part or one function object for the momentum part. `x` is a pair of coordinate
|
||||
* and momentum. The state is updated in-place.
|
||||
* - `do_step( sys , q , p , t , dt )` - This method is similar to the method above with the difference that the coordinate
|
||||
* and the momentum are passed explicitly and not packed into a pair.
|
||||
* - `do_step( sys , x_in , t , x_out , dt )` - This method transforms the state out-of-place. `x_in` and `x_out` are here pairs
|
||||
* of coordinate and momentum.
|
||||
*
|
||||
* \tparam NumOfStages Number of stages.
|
||||
* \tparam Order The order of the stepper.
|
||||
* \tparam Coor The type representing the coordinates q.
|
||||
* \tparam Momentum The type representing the coordinates p.
|
||||
* \tparam Value The basic value type. Should be something like float, double or a high-precision type.
|
||||
* \tparam CoorDeriv The type representing the time derivative of the coordinate dq/dt.
|
||||
* \tparam MomemtnumDeriv The type representing the time derivative of the momentum dp/dt.
|
||||
* \tparam Time The type representing the time t.
|
||||
* \tparam Algebra The algebra.
|
||||
* \tparam Operations The operations.
|
||||
* \tparam Resizer The resizer policy.

* \class runge_kutta_cash_karp54
|

* \brief The Runge-Kutta Cash-Karp method.
|
||||
*
|
||||
* The Runge-Kutta Cash-Karp method is one of the standard methods for
|
||||
* solving ordinary differential equations, see
|
||||
* <a href="http://en.wikipedia.org/wiki/Cash%E2%80%93Karp_methods">en.wikipedia.org/wiki/Cash-Karp_methods</a>.
|
||||
* The method is explicit and fulfills the Error Stepper concept. Step size control
|
||||
* is provided but continuous output is not available for this method.
|
||||
*
|
||||
* This class derives from explicit_error_stepper_base and inherits its interface via CRTP (current recurring template pattern).
|
||||
* Furthermore, it derivs from explicit_error_generic_rk which is a generic Runge-Kutta algorithm with error estimation.
|
||||
* For more details see explicit_error_stepper_base and explicit_error_generic_rk.
|
||||
*
|
||||
* \tparam State The state type.
|
||||
* \tparam Value The value type.
|
||||
* \tparam Deriv The type representing the time derivative of the state.
|
||||
* \tparam Time The time representing the independent variable - the time.
|
||||
* \tparam Algebra The algebra type.
|
||||
* \tparam Operations The operations type.
|
||||
* \tparam Resizer The resizer policy type.

*
|

* The Runge-Kutta Cash-Karp method is one of the standard methods for
|

* solving ordinary differential equations, see
|

* <a href="http://en.wikipedia.org/wiki/Cash%E2%80%93Karp_method">en.wikipedia.org/wiki/Cash-Karp_method</a>.
|
||||
* The method is explicit and fulfills the Error Stepper concept. Step size control
|
||||
* is provided but continuous output is not available for this method.
|
||||
*
|
||||
* This class derives from explicit_error_stepper_base and inherits its interface via CRTP (current recurring
|
||||
* template pattern). This class implements the method directly, hence the generic Runge-Kutta algorithm is not used.

* \brief The Runge-Kutta Dormand-Prince 5 method.
|
||||
*
|
||||
* The Runge-Kutta Dormand-Prince 5 method is a very popular method for solving ODEs, see
|
||||
* <a href=""></a>.
|
||||
* The method is explicit and fulfills the Error Stepper concept. Step size control
|
||||
* is provided but continuous output is available which make this method favourable for many applications.
|
||||
*
|
||||
* This class derives from explicit_error_stepper_fsal_base and inherits its interface via CRTP (current recurring
|
||||
* template pattern). The method possesses the FSAL (first-same-as-last) property. See
|
||||
* explicit_error_stepper_fsal_base for more details.

* \tparam Value The value type.

* \tparam Deriv The type representing the time derivative of the state.

* \tparam Time The time representing the independent variable - the time.
|

|

* \brief The Runge-Kutta Fehlberg 78 method.
|
||||
*
|
||||
* The Runge-Kutta Fehlberg 78 method is a standard method for high-precision applications.
|
||||
* The method is explicit and fulfills the Error Stepper concept. Step size control
|
||||
* is provided but continuous output is not available for this method.
|
||||
*
|
||||
* This class derives from explicit_error_stepper_base and inherits its interface via CRTP (current recurring template pattern).
|
||||
* Furthermore, it derivs from explicit_error_generic_rk which is a generic Runge-Kutta algorithm with error estimation.
|
||||
* For more details see explicit_error_stepper_base and explicit_error_generic_rk.
|
||||
*
|
||||
* \tparam State The state type.
|
||||
* \tparam Value The value type.
|
||||
* \tparam Deriv The type representing the time derivative of the state.
|
||||
* \tparam Time The time representing the independent variable - the time.
|
||||
* \tparam Algebra The algebra type.
|
||||
* \tparam Operations The operations type.
|
||||
* \tparam Resizer The resizer policy type.
