lorenz.ode: Lorenz system ODEs

In fractal: A Fractal Time Series Modeling and Analysis Package

Description

Ordinary differential equations fro the Lorenz system. See the help documentation for the lorenz data object for more information. A parameter space defined by sigma=10, r=28, and b=8/3 is known to produce chaotic motion.

Usage

lorenz.ode(x, sigma=10, r=28, b=8/3)

Arguments

x	a three-element numeric vector representing the current X, Y, and Z states, respectively, of the Lorenz system.
b	the b parameter. Default: 8/3.
r	the r parameter. Default: 28.
sigma	the sigma parameter. Default: 10.

Value

a vector of three values representing the Lorenz states X, Y, and Z, respectively, evaluated with the specified parameter regime.
