[sci.electronics] Dynamical systems simulation package available

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
