The Lorenz Equations

This is a numerical simulation of the Lorenz equations. These are a system of first order differential equations given by:

dx/dt = sigma (y-x)
dy/dt = rho x - y - xz
dz/dt = xy - beta z
These equations are integrated using a fourth order Runge Kutta method for the parameter values: sigma = 10.0, rho = 28.0, beta = 2.6667.

To restart the numerical integration of this system at time 0, click inside one of the graphical display windows. To pause/unpause a computation press the space bar while the mouse pointer is over the applet. Hit (almost) any other key to clear the drawing window.
