|  |      * \brief ODE Iterator with adaptive 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 from t_start | ||
|  |      * to t_end evaluated at steps with an adaptive step size dt. | ||
|  |      * After each iteration the iterator dereferences to a pair containing state | ||
|  |      * and time at the next time point t+dt where dt is controlled by the stepper. | ||
|  |      * This iterator can be used with ControlledSteppers 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_adaptive routine. | ||
|  |      * | ||
|  |      * adaptive_iterator is a model of single-pass iterator. | ||
|  |      * | ||
