E&F Chaos software

E&F Chaos is an easy-to-use software package for simulation of nonlinear dynamic models to investigate stability of steady states and the presence of periodic orbits and chaos by standard numerical simulation techniques such as time series, phase plots, bifurcation diagrams, Lyapunov exponent plots, basin boundary plots and graphical analysis.

Software 

The package contains many well-known nonlinear models, including applications in economics and finance, and is easy to use for non-specialists. New models and extensions or variations are easy to implement within the software package without the use of a compiler or other software.

E&F Chaos is developed to provide quick information about local and global dynamics and to aid formulating challenging research questions for further mathematical analysis.

Documentation

The functionality of E&F Chaos is described in detail in:

C. Diks, C.H. Hommes, V. Panchenko and R. van der Weide (2008) E&F Chaos: a user friendly software package for nonlinear economic dynamics, Computational Economics 32, 221-244.

A manual with a quickstart guide, 3 tutorials and a reference manual, is available both as a PDF file and in HTML for direct online viewing. The manual is written for version 1.00 but can be used without any problem with version 1.01; the only visual difference is that the `Load Model' and `Build New Model' options in the `File' menu have been swapped.
