All Implemented Interfaces:

ODE

Enclosing class:

ODEMultistepSolver

protected final class ODEMultistepSolver.InternalODE

extends java.lang.Object

implements ODE

A class that saves an internal state that may be different from the orginal ODE. This internal state is used with interpolation solvers.

Method Summary

void	getRate(double[] state, double[] rate) Gets the rate using the given state.
double[]	getState() Gets the state.
void	setInitialConditions() Sets the initial conditions using the current state of the ODE.
void	update() updates the ODE state using the engine's internal state.
