Detailed Description

template<typename SolverT>
class capd::poincare::TimeMap< SolverT >

TimeMap class provides methods for transport of sets (or points) by a given flow over some time interval.

Template parameter is an abstract solver of dynamical system. It is assumed that it provides methods for one-step transport (both for discrete and continuous case).

operator()() [1/3]

template<typename SolverT >

template<typename SetType >

VectorType capd::poincare::TimeMap< SolverT >::operator()	(	ScalarType	time,
		SetType &	theSet
	)

Integrates 'theSet' until time 'time'.

Parameters

[in,out]

theSet

- initial condition for integration. 'theSet.getCurrentTime()' should be an initial time for nonautonomous systems. On output 'theSet' represents solution to ODE at time 'time'

operator()() [2/3]

template<typename SolverT >

template<typename SetType >

VectorType capd::poincare::TimeMap< SolverT >::operator()	(	ScalarType	time,
		SetType &	theSet,
		MatrixType &	derivative
	)

Integrates 'theSet' until time 'time'.

Parameters

[in,out]	theSet	- initial condition for integration. 'theSet.getCurrentTime()' should be an initial time for nonautonomous systems. On output 'theSet' represents solution to ODE at time 'time'
[out]	derivative	monodromy matrix wrt to initial condition at time 'time'.

template<typename SolverT >

template<typename SetType >

VectorType capd::poincare::TimeMap< SolverT >::operator()	(	ScalarType	time,
		SetType &	theSet,
		SolutionCurve &	solution
	)

Integrates 'theSet' until time 'time'.

Parameters

[in,out]	theSet	- initial condition for integration. 'theSet.getCurrentTime()' should be an initial time for nonautonomous systems. On output 'theSet' represents solution to ODE at time 'time'
[out]	solution	- after successful integration becomes a functional object representing entire solution to ODE that can be evaluated at any intermediate time.
