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 email 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. (modified from the documentation)  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. (modified from the documentation)  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 PCBLUE 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 PCBLUE 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 PCBLUE collection which may be of interest to mathematicians:
PC/Blue Volume 424 COordinate GeOmetry [COGO] v1.22 Surveying/Engineering Application authorGeoCalc 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/pcblue/pcblue  David Meredith has uploaded an upgrade of his CC4.exe program to SIMTEL20. We have established a link to this new version:
cc49205.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 SF65101, 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). (modified from the documentation)  anumr5.zip (numerical.analysis, linear.algebra, calculus)
ANUM M. JeanMarie 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 Shupui 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. (Partly adapted from the documentation)  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 mailing list of this newsletter please send your email address to Larry. If you would like to submit program(s) and/or other appropriate material then get in contact with Earl or Larry for details.
