Lyap: A fortran 90 program to compute the Lyapunov exponents of a dynamical system from a time series Original Research Article

The program presented computes all the Lyapunov exponents of an unknown dynamical system from a time series. The method used is based on a fitting of the time series with an analytical function through a least square minimization, after which the Lyapunov exponents are determined from the stability of the trajectories calculated using this analytical function.
