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

i don't understand why this question is being down-ranked!

this is a homework problem, i don't really think its a research level problem. This question was assigned to us only after basics in matrix.
