Lyapunov exponent

[jhloh00]

Hello, I am a RATS user since ver.5..

I am looking for the method of Largest Lyapunov exponent to prove the Chaotic system in certain time series..

There are some chaos related libraries in Rats, for example R/S Statistics, Hurst exponent..but there is no Lyapunov related..

I ask code for this paper.."Michael T. Rosenstein, James J. Collins, and Carlo J. De Luca(1992), A practical method for calculating largest Lyapunov exponents from small data sets".

The URL of the paper is as follows
http://www.physionet.org/physiotools/ly ... einM93.pdf

there is matlab code for this paper..I'll attatch matlab file..this file is from EconPapers

I'll wait reply..

Thanks from Seoul..
