The best package for the PC for dynamical systems analysis that I know of is: Dynamical Systems Inc. PO Box 35241 Tucson AZ 85740 602-825-1331 The author is Dr. William Schaffer, who knows his stuff. The scope of the package is quite good. Discrete maps, two integrators with noise, bifurcation diagrams, phase space diagrams, Poincare sections, power analysis, fractal dimension calculation, data importation, good graphics. Requires a fortran compiler. The interface is from the dark ages, but with a promised upgrade. The following is a repost of an old new message: Article 662 of sci.math.symbolic: ================================================================ >From: bilbo@navajo.berkeley.edu (Bill Baringer) Newsgroups: sci.math,sci.electronics,sci.misc,sci.physics,sci.research,sci.math.num-analysis,sci.math.symbolic Subject: Dynamical systems simulation package available Keywords: Simulation, Chaos, Dynamical Systems Date: 6 Jun 89 04:53:15 GMT I thought I'd pass this on, in hopes that it would be of general interest. ============================================================================ INSITE is a collection of easy-to-use programs for the simulation and characterization of dynamical systems, with an emphasis on chaotic systems. INSITE runs on the X11 graphics package under UNIX and on the MetaGraphics graphics package under PC-DOS. There is a short write-up on it in the August 1987 issue of the Proceedings of the IEEE. It contains graphically based, interactive programs that: calculate and plot trajectories and orbits, calculate and plot bifurcation diagrams of continuous- or discrete-time systems, calculate Lyapunov exponents (via simulation), calculate correlation dimension of attractors (from a data file obtained via experiment or simulation), calculate and plot one-dimensional invariant manifolds of a (Poincare) map, calculate and plot periodic solution of continuous- or discrete-time systems, and calculate and plot phase portraits of two-dimensional continuous-time systems. The software is now available for distribution. The complete source code is included. Ordering information on the software can be obtained by writing INSITE P.O.
