The Encylopedia of Dynamical Systems at Scholarpedia is a good reference for all things dynamical. My Frequently Asked Questions on Nonlinear Science is somewhat out-of-date, but still has some elementary information.

Here is an (also out-of-date) list of software for dynamics. I will use a Macintosh for classroom demonstrations, and extensively use the software Maple and Matlab.

- Maple examples

(Students in this course are eligible for a Special Price for Maple Ask me for the code. - Matlab files
- to draw phase portraits of ODEs in 2D: dfield & pplane
- Vector Fields: vectorField.m (uses quiver for plots),
- Simple Numerical Methods: Euler.m (1st order Euler), ImprovedEuler.m (2nd order Euler), f.m (a typical ode),
- Lyapunov exponents for the Lorenz system: LorenzOneJet.m and LorenzLyp.m

- Mathematica Examples
- DynPac Dynamical Systems Package by Al Clark
- Rossler System
- Romeo and Juliet System
- Moore-Spiegel Attractor
