lorenzattractor {sindyr}

Simulate the Lorenz Attractor

Description

An implementation of the Lorenz dynamical system, which describes the motion of a possible particle, which will neither converge to a steady state, nor diverge to infinity; but rather stay in a bounded but 'chaotically' defined region, i.e., an attractor.

Usage

lorenzattractor(numsteps, dt, sigma, r, b)

Arguments

numsteps

The number of simulated points

dt

System parameter

sigma

System parameter

r

System parameter

b

System parameter

Value

It returns a matrix with the 3 dimensions of the Lorenz

Examples

## initialize the parameters
numsteps = 2 ^ 11; dt = .01; sigma = 10; r = 28; b = 8/3;

res = lorenzattractor(numsteps, dt, sigma, r, b)
