 | |
|      * \brief ODE Iterator with constant step size. The value type of this iterator is the state type of the stepper.
 | |
|      *
 | |
|      * 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.
 | |
|      *
 | |
|      * \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.
