Use the adaptive Runge-Kutta integrator to integrate a system of differential equations.
| tmin | Starting value of the independent variable. t is in the closed range [tmin, tmax] |
| tmax | Ending value for the independent variable. t is in the closed range [tmin, tmax] |
| hmin | Minimum step size, something like 1e-5 usually is good. Don't make this too big or you may not be able to get a stable solution |
| hmax | Maximum step size |
| eps_allowed | Maximum absolute error of any CV per step allowed. Don't make this parameter too big or you may not be able to get a stable solution. Also don't make it too small because then you are going to run into truncation error. |
| step_relax | The relaxation factor that is used in the step resizing algorithm. Should be less than 1.0; you can play with this parameter to improve the adaptive resizing, but should not be necessary. |
