Class template const_step_iterator

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


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

template<typename Stepper, typename System, typename State> 
class const_step_iterator {
  // construct/copy/destruct
  const_step_iterator(Stepper, System, State &, time_type, time_type, 
  const_step_iterator(Stepper, System, State &);


Implements an iterator representing the solution of an ODE from t_start to t_end evaluated at steps with 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_const routine.

const_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

  1. typename Stepper

    The stepper type which should be used during the iteration.

  2. typename System

    The type of the system function (ODE) which should be solved.

  3. typename State

    The state type of the ODE.

                        time_type t_end, time_type dt);
  2. const_step_iterator(Stepper stepper, System sys, State & s);
