- * \brief Integrates the ODE with observer calls at given time points.
- *
- * Integrates the ODE given by system using the given stepper. This function
- * does observer calls at the subsequent time points given by the range
- * times_start, times_end. If the stepper has not step size control, the
- * step size might be reduced occasionally to ensure observer calls exactly
- * at the time points from the given sequence. If the stepper is a
- * ControlledStepper, the step size is adjusted to meet the error bounds,
- * but also might be reduced occasionally to ensure correct observer calls.
- * If a DenseOutputStepper is provided, the dense output functionality is
- * used to call the observer at the given times. The end time of the
- * integration is always *(end_time-1).
- * If a max_step_checker is provided as StepOverflowChecker, a
- * no_progress_error is thrown if too many steps (default: 500) are
- * performed without progress, i.e. in between observer calls. If no
- * checker is provided, no such overflow check is performed.
- *
- * \param stepper The stepper to be used for numerical integration.
- * \param system Function/Functor defining the rhs of the ODE.
- * \param start_state The initial condition x0.
- * \param times_start Iterator to the start time
- * \param times_end Iterator to the end time
- * \param dt The time step between observer calls, _not_ necessarily the
- * time step of the integration.
- * \param observer Function/Functor called at equidistant time intervals.
- * \param checker [optional] Functor to check for step count overflows, if no
- * checker is provided, no exception is thrown.
- * \return The number of steps performed.
