public class ThreeEighthesIntegrator
- extends RungeKuttaIntegrator
This class implements the 3/8 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
1/3 | 1/3 0 0 0
2/3 |-1/3 1 0 0
1 | 1 -1 1 0
|--------------------
| 1/8 3/8 3/8 1/8
- Since:
- 1.2
