              vmm.ode.secondorder1D.ODE2ndOrder1D

All Implemented Interfaces:

java.util.EventListener, javax.swing.event.ChangeListener, Decorateable, Parameterizable

Direct Known Subclasses:

HarmonicOscillator, Pendulum

public abstract class ODE2ndOrder1D
extends ODE1stOrder2D

Represents a second order ODE exhibit x'' = f(x,x',t). This is subsumed under the ODE_2D first order class by the standard trick; namely setting x'(t) = y and y'' = f(x,y,t).
