Has anyone calculated Lyapunov Exponents (LE) using OpenTSTool? It says it calculates the Largest Lyapunov exponent by computing the average exponential growth of the distance of neighboring orbits via the prediction error. So, I am trying to plot Lyapunov exponents for Chua's oscillator that is showing chaotic behavior.

Hence, I am expecting a positive LE, a negative LE and a zero LE. But the plot I get is all positive values, and the values are pretty high as well, spanning fro 0 to 10. Can anyone tell me how to interpret this Lyapunov exponent plot?

Thanks.
