SpletLyapunov exponent is an essential tool in studying chaotic signal. Lyapunov exponent is the rate of the exponential separation with time of initially close trajectories. To illustrae … Splet30. maj 2024 · 1,567. 591. If the distance between nearby trajectories of a chaotic system grows like , with the Lyapunov exponent, then should have dimensions of reciprocal time, shouldn't it? The argument of an exponential function has to be dimensionless, otherwise the terms of the expansion. would have different dimensions.

How can I calculate the Lyapunov exponent?

Splet07. mar. 2011 · The Lyapunov exponent is a parameter characterizing the behavior of a dynamical system.
