Chris@16 94 * \brief Integrates the ODE with constant step size.
Chris@16 95 *
Chris@16 96 * This function is similar to integrate_const. The observer is called at
Chris@16 97 * equidistant time intervals t0 + n*dt.
Chris@16 98 * If the Stepper is a normal stepper without step size control, dt is also
Chris@16 99 * used for the numerical scheme. If a ControlledStepper is provided, the
Chris@16 100 * algorithm might reduce the step size to meet the error bounds, but it is
Chris@16 101 * ensured that the observer is always called at equidistant time points
Chris@16 102 * t0 + n*dt. If a DenseOutputStepper is used, the step size also may vary
Chris@16 103 * and the dense output is used to call the observer at equidistant time
Chris@16 104 * points. The final integration time is always t0 + num_of_steps*dt.
Chris@16 105 *
Chris@16 106 * \param stepper The stepper to be used for numerical integration.
Chris@16 107 * \param system Function/Functor defining the rhs of the ODE.
Chris@16 108 * \param start_state The initial condition x0.
Chris@16 109 * \param start_time The initial time t0.
Chris@16 110 * \param dt The time step between observer calls, _not_ necessarily the
Chris@16 111 * time step of the integration.
Chris@16 112 * \param num_of_steps Number of steps to be performed
Chris@16 113 * \param observer Function/Functor called at equidistant time intervals.
Chris@16 114 * \return The number of steps performed.
