Lyapunov exponent matlab codes

[Ali Abbasi]

Hello All
I am looking forward for Lyapunov exponent matlab codes for calculating variability in EMG and kinematics data in lower extremity during cycling. Is any body has these codes? I will be appreciate if any body send these codes to me.
Regards

You can download code from Wolf's algorithm from the NBCF website, http://www.unomaha.edu/biomech/nonlinearProgram.php.

Dear Friends
I do not know how I can calculate "dim = embedding dimension" and "tau = time lag" for Lyapunov exponent. I will be appreciate if any one help me about this.
Best Regards

Dear Ali,
embedding dimension for time series is usually calculated using General False Nearest Neighbor (GFNN). In addition, time delay could be calculated by Average Mutual Information (AMI) method.

For further information, have a look at Dr. Shelhamer's book: "nonlinear dynamics in physiology" or

"nonlinear time series analysis" by Kantz and Schriber.

Best,
