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.

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.
