The value of Lyapnov exponent is found using Wolf algorithm for step size of 0.01 and observation time of 10^5 in MATLAB 2020 using ode45 solver.
Try reducing the step size and repeating LLE calculation. it's not clear what system under your investigation.
I believe that your results can be interpreted as a periodic behavior.
Vyacheslav G. Rybin Thank you for your response. As suggested, I will recalculate the Lyapunov exponents with the reduced step size.
My question is not for any specific system. I wish to know the infimum value of the positive Lyapunov exponent for a system.
