All Implemented Interfaces:

FirstOrderIntegrator, Named

public class GillIntegrator
extends RungeKuttaIntegrator
implements Named

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)
