LP-VIcode: La Plata Variational Indicators Code

LP-VIcode computes variational chaos indicators (CIs) quickly and easily. The following CIs are included:

Lyapunov Indicators, also known as Lyapunov Characteristic Exponents, Lyapunov Characteristic Numbers or Finite Time Lyapunov Characteristic Numbers (LIs)

Mean Exponential Growth factor of Nearby Orbits (MEGNO)

Slope Estimation of the largest Lyapunov Characteristic Exponent (SElLCE)

Smaller ALignment Index (SALI)

Generalized ALignment Index (GALI)

Fast Lyapunov Indicator (FLI)

Orthogonal Fast Lyapunov Indicator (OFLI)

Spectral Distance (SD)

dynamical Spectra of Stretching Numbers (SSNs)

Relative Lyapunov Indicator (RLI)
