/**
|

* \class n_step_time_iterator
|
|
*
|
|
* \brief ODE Iterator with constant step size. The value type of this iterator is a std::pair containing state and time.
|
|
*
|
|
* Implements an iterator representing the solution of an ODE starting from t
|
|
* with n steps and a constant step size dt.
|
|
* After each iteration the iterator dereferences to a pair of state and time at the next
|
|
* time t+dt.
|
|
* This iterator can be used with Steppers and
|
|
* DenseOutputSteppers and it always makes use of the all the given steppers
|
|
* capabilities. A for_each over such an iterator range behaves similar to
|
|
* the integrate_n_steps routine.
|
|
*
|
|
* n_step_time_iterator is a model of single-pass iterator.
|
|
*
|
|
* The value type of this iterator is pair of state and time.
|
|
*
|
|
* \tparam Stepper The stepper type which should be used during the iteration.
|
|
* \tparam System The type of the system function (ODE) which should be solved.
|
|
* \tparam State The state type of the ODE.
