public class GillIntegrator
- extends RungeKuttaIntegrator
This class implements the Gill fourth order Runge-Kutta
integrator for Ordinary Differential Equations .
This method is an explicit Runge-Kutta method, its Butcher-array
is the following one :
0 | 0 0 0 0
1/2 | 1/2 0 0 0
1/2 | (q-1)/2 (2-q)/2 0 0
1 | 0 -q/2 (2+q)/2 0
|-------------------------------
| 1/6 (2-q)/6 (2+q)/6 1/6
where q = sqrt(2)
