ABOUT THIS SOFTWARE

This software is designed for use with Edward Scheinerman's undergraduate
textbook "Invitation to Dynamical Systems" published by Prentice-Hall.
The software is copyright (c) 1995 by Edward R. Scheinerman. It may be
used freely by anyone who owns a copy of the aforementioned text.

This software was created with and designed to be used with MATLAB
(version 4.0 or higher).

If you would like to view this information from within MATLAB, copy the
contents of the diskette into a subdirectory or folder of your MATLAB
directory or folder and make sure that the directory or folder is on your
MATLAB path.  From within MATLAB, cd to that directory or folder and enter
"type readme" at the MATLAB prompt.

OBTAINING THE SOFTWARE

These programs are available on disk -- just complete and mail the postcard
included with your copy of "Invitation to Dynamical Systems". Be sure to
select the computing platform (Mac or Windows) you prefer.

The programs are also available via FTP on the Internet from either

ftp.mathworks.com  in the directory  /pub/books/scheinerman

or 

brutus.mts.jhu.edu   in the directory /pub/scheinerman/invitation/software

If you use a Unix machine, you can copy the binary file "soft.tar"
from the /pub/scheinerman/invitation directory on brutus.mts.jhu.edu
to your own machine. Put "soft.tar" in its own directory and then give the
command

tar xf soft.tar

All the files will then be unpacked and you can then delete the "soft.tar"
file.


ON THE WEB

You may also like to visit the "Invitation to Dynamical Systems" home page on
the World Wide Web. The URL is

http://www.mts.jhu.edu/~ers/invite.html

This page provides access to the software FTP archives as well as other
useful information and some pretty pictures.


GETTING STARTED

First, nearly all the programs are designed to be run under MATLAB. 
MATLAB is produced by The MathWorks (info@mathworks.com). A student edition
of MATLAB is available through Prentice-Hall -- contact your book shop for
details. At present, a discount is given if the student version of MATLAB is
purchased together with a Prentice-Hall book (such as "Invitation to
Dynamical Systems").

Second, a User's Guide is included in the "docs" directory (folder). Three

versions of the Guide can be found there:

* guide.tex	A LaTeX source file for the Guide. If you have TeX,
		run latex on this file and print it out.

* guide.ps	If you do not have TeX, but have access to a PostScript
		printer, print this version.

* guide.txt	If all else fails, this is a "plain text" (ASCII) version
		of the Guide. This version will work on any computer and
		on any printer.
