class pyoculus.solvers.lyapunov_exponent.LyapunovExponent(problem, nsave=20, every=100)

Class for computing the Lyapunov Exponent

compute(x, eps=None, base=np.float64(2.718281828459045))

Compute the maximal Lyapunov exponents

10. 3. Sprott, Chaos and Time-Series Analysis (Oxford University Press, 2003), pp.116-117.

Parameters:

• x – the initial point

• eps – the perturbation, default is a random direction with norm of the square root of the machine precision

• base – the base of the logarithm, default is exp(1)

Returns:

the maximal Lyapunov exponents

Return type:

np.array
