Journal reference: Comput. Phys. Commun. 178(2008)788
Programming language: Scilab 3.1.1.
Computer: PC-compatible running Scilab on MS Windows or Linux.
Operating system: Windows XP, Linux.
RAM: below 100 Megabytes
Keywords: Lyapunov exponent, Kolmogorov-Sinai entropy, power spectrum, autocorrelation, phase portrait, ODE, nonlinear dynamics.
PACS: 01.50.H-, 05.45-a.
Classification: 6.2.

Nature of problem:
Any physical model containing linear or nonlinear ordinary differential equations(ODE).

Solution method:
Numerical solving of ordinary differential equations. The chaotic behavior of the nonlinear dynamical system is analyzed using Poincaré sections, phase-space maps, autocorrelation functions, power spectra, Lyapunov exponents and Kolmogorov-Sinai entropies.

Restrictions:
The package routines are normally able to handle ODE systems of high orders (up to order twelve and possibly higher), depending on the nature of the problem.

Running time:
10 to 20 seconds for problems that do not involve Lyapunov exponents calculation; 60 to 1000 seconds for problems that involve high orders ODE and Lyapunov exponents calculation.
