Class template n_step

Class template n_step_iterator

boost::numeric::odeint::n_step_iterator — ODE Iterator with constant step size. The value type of this iterator is the state type of the stepper.

Synopsis

// In header: <boost/numeric/odeint/iterator/n_step_iterator.hpp>

template<typename Stepper, typename System, typename State> 
class n_step_iterator {
public:
  // construct/copy/destruct
  n_step_iterator(Stepper, System, State &, time_type, time_type, size_t);
  n_step_iterator(Stepper, System, State &);
};

Description

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 the state x 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_iterator is a model of single-pass iterator.

The value type of this iterator is the state type of the stepper. Hence one can only access the state and not the current time.

Template Parameters

```
typename Stepper
```
The stepper type which should be used during the iteration.
```
typename System
```
The type of the system function (ODE) which should be solved.
```
typename State
```
The state type of the ODE.
