- All Implemented Interfaces:
FirstOrderIntegrator
,ODEIntegrator
This class implements the classical fourth order Runge-Kutta
integrator for Ordinary Differential Equations (it is the most
often used Runge-Kutta method).
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 | 0 1/2 0 0 1 | 0 0 1 0 |-------------------- | 1/6 1/3 1/3 1/6
