Earl Fife, Professor of Mathematics at Calvin College, Grand Rapids,
MI has agreed to become moderator of the macintosh section of the
Mathematics Archives at WUARCHIVE. Earl has been placing and listing
public domain / shareware macintosh software in subdirectories of
/edu/math/mac which can be used in the teaching of mathematics at
the college / university level. If you are the author of a package
which you think is appropriate for the Mathematics Archive then
contact Earl if it runs on the macintosh and Larry if it runs on an
msdos computer. Our e-mail addresses are listed above. In addition,
If there is a macintosh or msdos public domain / shareware package
which you believe should be listed in the Mathematics Archives then
contact one of us. We hope to expand the offerings at Mathematics
Archives in the future not only to include software but other also
other items which would be useful in the teaching of mathematics.
For example, we want to include reports, newsletters, etc. about
calculus reform in the subdirectory calculus.reform. We solicit
your comments, ideas, etc.

Earl will send out a separate newsletter of updates of the macintosh
section. Contact him if you want to be placed on the mailing list
for that newsletter. If you want to be added to the mailing list
for the msdos newsletter contact Larry.

The following is a list of recent additions and lisitings of msdos
software in Mathematics Archives. Instructions for downloading files
are given at the end of this article.
----------------------------------------------------------------------
The following demo has been added to the msdos archives:

chaosdem.zip (dynamics, diff.equations)

CHAOS DEMONSTRATIONS 1.1
JULIEN C. SPROTT
Department of Physics
University of Wisonsin
Madison, WI 53706
GEORGE ROWLANDS
Department of Physics
University of Warwick
Coventry CV47AL, England
CHAOS DEMONSTRATIONS is a collection of eighteen demonstrations
illustrating chaos in physical and biological systems including the
driven pendulum, van der Pol's equation, three body problem, Lorenz
attractor, logistic equation, fractals, diffusion, etc. The goal of
the program is to encourage an appreciation of the complexity and
beauty of even simple systems, not only for the professional
scientist, but also for the interested nonspecialist. You can sit
back and watch the demonstrations cycle through an automatic
sequence, or in the complete version of the program you can take
control and examine in detail the effect of varying the parameters.
CHAOS DEMONSTRATIONS is published by the American Institute of
Physics as part of a continuing series of software from Physics
Academic Software. Copyright 1990 by the American Institute of
Physics. All rights reserved. Portions copyright 1989 by Julien C.
Sprott. All rights reserved.

There is another demo which has been recently uploaded to the
SIMTEL20 Archives:

maplev.zip (calculus, linear.algebra, algebra)

A QUICK TOUR OF MAPLE
Copyright(c) 1991 by Waterloo Maple Software

Maple is an essential tool for anyone who needs to use or study
mathematics. The demo on this disk will give you a glimpse of a
few of the over 2000 Maple functions and what they can do for you.
To run the demo on your computer, you will need an 80386 or 80486
based personal computer with 2MB or more memory and a CGA, EGA,
VGA, or Hercules display adapter (for the graphics commands only).
When you first start the Maple Demonstration, a copyright message
and ordering information window will appear on your screen. After
you have read the copyright notice, you can press one of two keys
to begin. If you press Enter, the demo will automatically type in
the examples for you. If you press the Space bar instead, the demo
will run just like a full Maple session; you type the commands you
want to execute. In either case, you will be dealing with a real
subset of Maple. This is NOT a recorded demo. The time it takes
to solve each problem is the same as a full version of Maple would
require to solve the same problem on your machine. Note that the
Demonstration version of Maple contains only those portions of
Maple necessary to run the Maple commands used in this Tour.

There are a couple of other symbolic mathematics packages which are
mirrored at WUARCHIVES. The first from the archives at the
University of Michigan is a program from the Netherlands:

form.arc (calculus, linear.algebra, algebra)

FORM
J.A.M.Vermaseren
FORM is a symbolic manipulation program that has been designed for
large scale formula manipulation. The formulae that can be handled
by FORM are in principle only limited in size by the available disk
space. In addition FORM is optimized for speed, enabling it to deal
with these giant formulae in relatively little time. FORM runs as
a batch program. One of the features of FORM is the management of
really large formulae in a very efficient way. This is version 1
which is free; an improved version 2 is a commercial package (e-
mail contact can@can.nl).
(modified from the documentation)
----------------------------------------------------------------------
The second symbolic mathematics package is in the PC-BLUE collection

vol546.zip (calculus, algebra)

PFSA - Symbolic Algebra Program
Dr Donald Stevens
The PFSA program was created to do some rather large but
simple algebraic computations. PFSA does not have the large
variety of commands which more general purpose symbolic algebra
programs (muMath and Macsyma) have but it is faster and can work
with bigger expressions. PfSA ran 90 times faster than Macsyma on
a very large Hamiltonian canonical transformation project, and it
runs more than 200 times faster than muMath when doing example E.
PFSA is written in Fortran and the arithmetic involving
coefficients of terms is done with the Fortran arithmetic. Two
versions are provided, one which uses only rational integer*4
arithmetic (PFSAI.EXE) and another (PFSAF.EXE) which uses real*8
arithmetic during calculation of coefficients.
This is a program contained in the PC/Blue Library, compiled
and distributed by the New York Amateur Computer Club, Inc, Box
3442, Church St Station, New York, NY 10008.
(modified from the documentation)
---------------------------------------------------------------------
There is another package in the PC-BLUE collection which may be used
in the teaching of mathematics:

vol370.zip (numerical.partial.diff.eq)

Laplace Equation in 2 Dimensions
James R Van Zandt
LAPLACE solves Laplace's equation in two dimensions, with
Dirichlet boundary conditions on arbitrary boundaries. LAPLACE
calculates the potentials on a rectangular equally spaced grid of
W * H points ranging from XMIN to XMAX and from YMIN to YMAX. The
user may use switch options to initialize these six parameters. C
source code is included.
This is one of two programs (the other program is an
accounting program) contained in the PC/Blue Library, compiled and
distributed by the New York Amateur Computer Club, Inc, Box 3442,
Church St Station, New York, NY 10008.
(modified from the documentation)
---------------------------------------------------------------------
There are two other disks in the PC-BLUE collection which may be of
interest to mathematicians:

PC/Blue Volume 424 COordinate GeOmetry [COGO] v1.22
Surveying/Engineering Application
author-GeoCalc Software Systems Co.
PC/Blue Volume 461 Linear Cellular Automata
compiled by Harold V McIntosh
They can be found along with other PC BLUE disks in the directory
mirrors/pc-blue/pcblue
--------------------------------------------------------------------
David Meredith has uploaded an upgrade of his CC4.exe program to
SIMTEL20. We have established a link to this new version:

cc4-9205.zip (calculus, linear.algebra)

There is a substantial modification on graphing and the handling of
matrices.
---------------------------------------------------------------------
I found two programs for those who use Microsoft Windows:

mathgraf.zip (miscellaneous)

Mathgraf 2.4.1
Copyright 1991, Patrick Robin
Mathgraf is a shareware windows program which displays the
graphs of functions. You need to have Microsoft Windows in order to
run this program.
---------------------------------------------------------------------
logstc11.zip (dynamics)

LOGISTIC.EXE
Copyright (c) 1992 by Guillermo Payet
LOGISTIC plots, and lets you zoom into, the bifurcation diagram of
the logistic equation. It is a sharweware program which runs under
Microsoft Windows 3.0 (or later) which is required.
(adapted from the documentation)
---------------------------------------------------------------------
There is another Windows package which is written for a biology class
but may be useful for a modelling course:

rsistn62.zip (modelling)

Resistan 6.2
Simulation by Phil A. Arneson
Program by Barr E. Ticknor
Department of Plant Pathology
Cornell University
Ithaca, NY 14853
Copyright 1992 Cornell University All rights reserved.
Resistan is a mechanistic simulation of the selection of fungicide
resistance (Arneson, et al., 1988). The simulation has been
written for the Microsoft Windows environment (ver. 3.0 or higher)
which is required in order to run the program.
(adapted from the documentation)
-------------------------------------------------------------------
Some other packages which were found and which may be useful are:

tsdraw14.arc (college.algebra, dicrete.math)

TSDRAW 1.4
Prof. Timo Salmi
School of Business Studies
University of Vaasa
SF-65101, Finland

Drawing system for linear equations and Linear Programming
problems. It is a complete drawing system with its own command
language. To give a simple example you can draw the line 2x + 3y =
6 by giving the command li 2,3,6, and the line will be displayed on
the coordinate system. The program has the options of entering the
input from the keyboard or from a file. The system is not actually
limited to drawing lines, but that is what Prof. Salmi uses when
teaching budgeting with linear programming in a classroom with an
overhead projector to display the computer images of the relevant
tasks (examples are included in the package).

-------------------------------------------------------------------
anumr5.zip (numerical.analysis, linear.algebra, calculus)

ANUM
M. Jean-Marie de Montarby
40 avenue des Tilleuls
75016 PARIS, FRANCE
ANUM is a library for use with one of the following C
compilers: Turbo C 2.0, Turbo C++ 1.0 or Borland C++ 2.0 from
Borland International. C source code is provided for complex
numbers, solutions of polynomials, solutions of ordinary
differential equations, linear algbra, integration, least squares
fit.
(modified from documentation)
--------------------------------------------------------------------
matrix04.zip (numerical.analysis, linear.algebra)

Small Matrix Toolbox for C programmers
version 0.4
by Patrick Ko Shu-pui
Hong Lok Yuen,
Tai Po, Hong Kong
Copyright (c) 1992 All Rights Reserved.
A collection of C routines for elementary matrix algebra.
---------------------------------------------------------------------
predict.arc (modelling)

Predictor 1.0
Mark Sokolowski
Outremont, Quebec

Predictor is an interpolation program that can be used to
indicate the possible evolution of a curve made up of a
correlated set of points. Can use a mouse. The user may enter
or delete points and see the curve which interpolates the
resulting collection of points. However, there is no indication
of the method nor of the function used.

WUARCHIVE at Washington University at St. Louis is now a site for the
storage of public domain and shareware software and other materials
which can be utilized in the teaching of mathematics at the college
and university levels.

To access these files, use anonymous FTP to wuarchive.wustl.edu,
switch to the subdirectory /edu/math/msdos if you are interested
in software which can be used on msdos computers or switch to the
subdirectory /edu/math/mac for software which can be used on
macintosh computers. Change to the subdirectory which is the subject
area for which you would like to obtain software. In each subject
area there is a file 00info.txt which contains a listing of all
programs in the area together with a short abstract similar to the
above abstracts.

If you have any comments, suggestions about, problems with, etc.
the Mathematics Archives, please contact one of the moderators
(macintosh) Earl Fife at fife@calvin.edu or (msdos) Larry Husch
at husch@wuarchive.wustl.edu If you want to be added to the
