public abstract class RungeKuttaIntegrator extends AbstractIntegrator
These methods are explicit Runge-Kutta methods, their Butcher arrays are as follows :
0 | c2 | a21 c3 | a31 a32 ... | ... cs | as1 as2 ... ass-1 |-------------------------- | b1 b2 ... bs-1 bs
|Modifier and Type||Method and Description|

public double integrate(FirstOrderDifferentialEquations equations, double t0, double y0, double t, double y) throws DerivativeException, IntegratorException
This method solves an Initial Value Problem (IVP).
Since this method stores some internal state variables made
available in its public interface during integration (
ODEIntegrator.getCurrentSignedStepsize()), it is not thread-safe.
equations- differential equations to integrate
t0- initial time
y0- initial value of the state vector at t0
t- target time for the integration (can be set to a value smaller than
t0for backward integration)
y- placeholder where to put the state vector at each successful step (and hence at the end of integration), can be the same object as y0
EventHandlerstops it at some point.
DerivativeException- this exception is propagated to the caller if the underlying user function triggers one
IntegratorException- if the integrator cannot perform integration
