Iterate! ver 3.11 Copyright 1993 by Brent Hugh
Description of the program
─────────────────────────────────────────────────────────────────────────────
Iterate! is a program that graphs iterated functions. Iterate! demonstrates
chaos theory (since--mathematically speaking--chaos is made with iterated
functions) and fractals (many of the graphs Iterate! makes are fractals).
Iteration theory--which Iterate! is based on--is the same theory that is used
to draw Mandelbrot Sets and Julia Sets. Iterate!'s ability to draw Julia Sets
and iterate the points in and around the set makes it a powerful--and fun--tool
for exploring this fascinating area of mathematics. With Iterate!, you'll see
Julia Sets in a way you've never seen them before.
But Iterate! doesn't just do Julia Sets. It has a wide variety of other
functions that illustrate aspects of iteration theory and chaos, as well as a
function interpreter so you can try out your own functions.
Features
─────────────────────────────────────────────────────────────────────────────
Here are some of the best features of Iterate!:
* A wide variety of built in functions that you can try
* A user function interpreter, so you can write your own functions
* Ability to easily save graphs to disk and later restore them
* Ability to quickly zoom in on a certain part of the screen, or zoom out
* Full support of the mouse, both for selecting points to iterate, and for
zooming the window in and out
* An iteration stack for automatic calculation of graphs with lengthy
iteration times
* Most graphics modes and cards supported
Files included

Program distribution
─────────────────────────────────────────────────────────────────────────────
Iterate! is distributed as shareware. Please copy and distribute to friends,
Users' Groups, BBS's, etc.
If you use Iterate!, you should register it. See Iterate!.txt for more
details.
Registered users will receive a disk with the latest version of Iterate!, a
version of Iterate! optimized for 286 and better CPUs, the source code for
Iterate!, a Mandelbrot-Julia generator that works together with Iterate!, and
several other programs I have written that illustrate fractals and chaos
(including a 3-D fractal generating program).
