Appendix 1 Mupad Libraries and Procedures Appendix 1 MuPAD Libraries and Procedures In this appendix I have included all the libraries available in MuPAD, and almost all the procedures that are available in the most current version of MuPAD at the time of writing. I have tried to make this list as complete as it was possible. However, I could have missed a few things. There are many procedures that are either undocumented or considered to be internal. However, the border between internal procedures and those that are designated to be used by MuPAD users can be a bit dim. So, some of the procedures described here might also be internal and some other can become internal in the future. In fact, from the user's point of view there is little difference between internal and official procedures. You can use them, as long as you know their syntax and where to find them. For many procedures, I have provided a short syntax and description that may help the readers to identify the role of the procedure or find a procedure for a specific goal. You need to keep in mind that most of these procedures can be used in a wide variety of ways with a number of parameters. It is therefore not possible to describe in a small chapter all the forms of syntax and parameters that can be applied to them. My intention while developing this appendix was to provide you with the most basic information about what you can find in MuPAD's libraries and in the whole MuPAD system. There is huge number of procedures that I have grouped under the title "MuPAD Standard Collection". In fact, these procedures are not always included in any particular library; they are placed in various parts of the MuPAD system. However, you can access them directly without using the slot operator regardless of where they really are. Thus, if you can use a procedure like this, f1oat(1+exp(J)) but not like this, comb; nat: : bell (I5), then I will consider this procedure as a part of the so-called standard collection. Many of the procedures listed here were not even mentioned in my book. You can find information about them through MuPAD's help. My intention was to use this appendix instead of an index. Thus, 14 MuPAO Pro Computing Essentials MuPAD objects that I have described in this book shall have a page number attached, where you can find more information about them. The order of libraries and procedures is alphabetic.

  • Rapid Research with Computer Algebra Systems
    doi: 10.21495/71-0-109 25th International Conference ENGINEERING MECHANICS 2019 Svratka, Czech Republic, 13 – 16 May 2019 RAPID RESEARCH WITH COMPUTER ALGEBRA SYSTEMS C. Fischer* Abstract: Computer algebra systems (CAS) are gaining popularity not only among young students and schol- ars but also as a tool for serious work. These highly complicated software systems, which used to just be regarded as toys for computer enthusiasts, have reached maturity. Nowadays such systems are available on a variety of computer platforms, starting from freely-available on-line services up to complex and expensive software packages. The aim of this review paper is to show some selected capabilities of CAS and point out some problems with their usage from the point of view of 25 years of experience. Keywords: Computer algebra system, Methodology, Wolfram Mathematica 1. Introduction The Wikipedia page (Wikipedia contributors, 2019a) defines CAS as a package comprising a set of algo- rithms for performing symbolic manipulations on algebraic objects, a language to implement them, and an environment in which to use the language. There are 35 different systems listed on the page, four of them discontinued. The oldest one, Reduce, was publicly released in 1968 (Hearn, 2005) and is still available as an open-source project. Maple (2019a) is among the most popular CAS. It was first publicly released in 1984 (Maple, 2019b) and is still popular, also among users in the Czech Republic. PTC Mathcad (2019) was published in 1986 in DOS as an engineering calculation solution, and gained popularity for its ability to work with typeset mathematical notation in combination with automatic computations.

Abstract We rep ort on some exp eriences with the general purp ose Computer Algebra Systems (CAS) Axiom, Macsyma, Maple, Mathematica, MuPAD, and Reduce solving systems of p olynomial equations and the way they present their solutions. This snapshot (taken in the spring 1996) of the current power of the di erent systems in a sp ecial area concentrates b oth on CPU-times and the quality of the output. 1 Intro duction Let S := k [x ;::: ;x ] be the p olynomial ring in the variables x ;::: ;x over the eld 1 n 1 n k and B := ff ;::: ;f g S be a nite system of p olynomials. Denote by I (B ) the 1 m ideal generated by these p olynomials.

Splitting the system into smaller ones, solving them separately, and patching all solu- tions together is often a go o d guess for a quick solution of even highly nontrivial problems. This can b e done by several techniques, e.g. characteristic sets, resultants, the Grobner fac- torizer or some ad ho c metho ds.

    J. Symbolic Computation (1998) 25, 127–159 A Survey of User Interfaces for Computer Algebra Systems NORBERT KAJLER† AND NEIL SOIFFER‡§ †Ecole des Mines de Paris, 60 Bd. St-Michel, 75006 Paris, France ‡Wolfram Research, Inc., 100 Trade Center Drive, Champaign, IL 61820, U.S.A. This paper surveys work within the Computer Algebra community (and elsewhere) di- rected towards improving user interfaces for scientific computation during the period 1963–1994. It is intended to be useful to two groups of people: those who wish to know what work has been done and those who would like to do work in the field. It contains an extensive bibliography to assist readers in exploring the field in more depth. Work related to improving human interaction with computer algebra systems is the main focus of the paper. However, the paper includes additional materials on some closely related issues such as structured document editing, graphics, and communication protocols. c 1998 Academic Press Limited 1. Introduction There are several problems with current computer algebra systems (CASs) that are interface-related. These problems include: the use of an unnatural linear notation to enter and edit expressions, the inherent difficulty of selecting and modifying subexpressions with commands, and the display of large expressions that run off the screen. These problems may intimidate novice users and frustrate experienced users. The more natural and intuitive the interface (the closer it corresponds to pencil and paper manipulations), the more likely it is that people will want to take advantage of the CAS for its ability to do tedious computations and to verify derivations.

  • Introduction Computer Algebra Systems
    Introduction Reading Problems Computer Algebra Systems Computer Algebra Systems (CAS) are software packages used in the manipulation of math- ematical formulae in order to automate tedious and sometimes difficult algebraic tasks. The principal difference between a CAS and a traditional calculator is the ability of the CAS to deal with equations symbolically rather than numerically. Specific uses and capabilities of CAS vary greatly from one system to another, yet the purpose remains the same: ma- nipulation of symbolic equations. In addition to performing mathematical operations, CAS often include facilities for graphing equations and programming capabilities for user-defined procedures. Computer Algebra Systems were originally conceived in the early 1970’s by researchers work- ing in the area of artificial intelligence. The first popular systems were Reduce, Derive and Macsyma. Commercial versions of these programs are still available. The two most commercially successful CAS programs are Maple and Mathematica. Both programs have a rich set of routines for performing a wide range of problems found in engineering applications associated with research and teaching. Several other software packages, such as MathCAD and MATLAB include a Maple kernal for performing symbolic-based calcu- lation. In addition to these popular commercial CAS tools, a host of other less popular or more focused software tools are availalbe, including Axiom and MuPAD. The following is a brief overview of the origins of several of these popular CAS tools along with a summary of capabilities and availability. Axiom Axiom is a powerful computer algebra package that was originally developed as a research tool by Richard Jenks’ Computer Mathematics Group at the IBM Research Laboratory in New York.

  • Computer Algebra Systems and Undergraduate Mathematics Curriculum
    Computer Algebra Systems and Undergraduate Mathematics Curriculum Miroslaw Majewski Zayed University [email protected] Abstract. In recent years, we faced a number of changes in undergraduate mathematics curriculum. This process was a bit different in each country but the general idea was to accommodate in undergraduate mathematics curriculum topics that are relevant to our times. In many countries, selected topics, which usually were taught in university courses, were moved to the high school curriculum and some classical mathematical topics disappeared completely from high school and even from university. Unfortunately, such changes very rarely addressed issues of using computers in teaching mathematics. The main objective of this paper is to analyse teaching of mathematics from a computing point of view; to highlight changes or at least potential changes in the mathematics curriculum that follow from using computer applications and especially Computer Algebra Systems; to investigate some of the changes in how we teach mathematics; and to describe new skills that our students acquire from these changes. Introduction Teaching mathematics with a computer is becoming a popular trend and it has many different flavours. There are people who teach mathematics in the traditional way and use computers sporadically to illustrate certain topics. At the other end of this spectrum, there are teachers and university professors who use computers as much as possible and sometimes change the curriculum to include topics that earlier were never included in mathematics curriculum (see [6,7,9]). We all know of topics that could not be taught with the traditional paper-and-pencil methods, but which can now be presented and explored easily with the help of computers.

  • Stuck Behind the Math
    Stuck Behind the Math both student learning and interest, survey results from Becker and Watts (1995, Stuck Behind the Math: Just 1996, 2001) indicate that the transition to technology-based instruction has not been widely adopted by economics college instructors. According to Becker and How Helpful Can One Expect Watts, instruction in the typical undergraduate economics classroom is still based primarily on lectures, with the chalkboard and text assignments as complements. This is particularly true of courses in which conceptual ideas and more rigorous Technology to be in the mathematical models are stressed, most notably, the intermediate micro and macroeconomic theory courses.We believe that the lack of uniformity in Economics Classroom? transitioning to technology-based pedagogy stems from an incomplete understanding of the benefits of technology in addition to a perception that the start-up costs associated with its incorporation are high. Our paper addresses both of these issues. Frank Raymond, Anne Raymond and Myra McCrickard First, we use pedagogical research in economics and mathematics to understand how technology aids learning and to discuss why some classroom objectives may be achieved more easily when technology is used to complement lecture material. Abstract Although instructors of economics have begun to incorporate insights from learning theory into teaching pedagogy (notably Goffe and Sosin, 2005), existing This paper studies the efficacy and motivation for using technology when research in psychology and education has much more to offer when attempting to explaining mathematical concepts in economics pedagogy. It links practice with assess the benefits of technology. Given the degree to which economic theory has theory by examining the use of technology in light of current literature on active come to rely on mathematical tools, it follows that the abundance of research in and cooperative learning in economics in conjunction with extensive research in mathematics education is particularly appropriate.

In general terms, CAS all deal with mathematical objects represented in symbolic form. Some, but not all, also provide interfaces to routines for numerical computation; some, but again not all, provide interfaces to graphical routines for visualization of math- ematical objects. Almost all of them provide programming languages to allow users to extend the packages’ functionality. All of them aim, in one way or another, to be “systems for doing mathematics by computer” as Stephen Wolfram’s Mathematica package [15] boldly proclaims. 1. Historical development of CAS The following discussion is meant to illustrate the range of such systems that have been created. It does not aim to be exhaustive, and the author apologizes in advance to anyone whose contributions have been omitted or overlooked. The first computer algebra systems in effect grew out of artificial intelligence research starting in the 1960s, but connections with that side of computer sci- ence have lessened over time.

Abstract Symbolic Computation and Satisfiability Checking are viewed as individual research areas, but they share common interests in the development, implementation and application of decision procedures for arithmetic theories. Despite these commonalities, the two communities are currently only weakly con- nected. We introduce a new project SC2 to build a joint community in this area, supported by a newly accepted EU (H2020-FETOPEN-CSA) project of the same name. We aim to strengthen the connection between these communities by creating common platforms, initiating interaction and exchange, identi- fying common challenges, and developing a common roadmap. This abstract and accompanying poster describes the motivation and aims for the project, and reports on the first activities. 1 Introduction We describe a new project to bring together the communities of Symbolic Computation and Satisfiability Checking into a new joint community, SC2. Both communities have long histories, as illustrated by the tool development timeline in Figure 1, but traditionally they do not interact much even though they are now individually addressing similar problems in non-linear algebra.
