        of an ODE to obtain <span class="emphasis"><em>x(t+dt)</em></span> using a given step size
        <span class="emphasis"><em>dt</em></span>. Basic steppers can be Runge-Kutta steppers, symplectic
        steppers as well as implicit steppers. Depending on the actual stepper, the
        ODE is defined as <a class="link" href="system.html" title="System">System</a>,
