All Implemented Interfaces:

Node

public class Diffusion_a
extends Reactor

The first order ordinary differential equation is solved using analytic equation. The tau and infinity is assumed constant during dt. This class doesn't work under Runge-Kutta, use Diffusion.java instead. Created on 2004/05/26
