Paul Bryant (C) 2009, LyapOde (Version 4): Includes source code written in "C" for calculation of Lyapunov exponents when the differential equations are known. Can also calculate the conditional Lyapunov exponents for coupled identical systems. The software can be compiled for running on Windows, Mac, or Linux/Unix systems. Includes the equations for several systems (Lorenz, Rossler, etc.) and documentation on how to create and compile software for additional systems of the user's choice.
