Computer Algebra and Symbolic Computation: Elementary Algorithms [Hardcover]

Joel S. Cohen (Author)

Book Description

ISBN-10: 1568811586 | ISBN-13: 978-1568811581 | Publication Date: July 19, 2002 | Edition: Har/Cdr

This book provides a systematic approach for the algorithmic formulation and implementation of mathematical operations in computer algebra programming languages. The viewpoint is that mathematical expressions, represented by expression trees, are the data objects of computer algebra programs, and by using a few primitive operations that analyze and construct expressions, we can implement many elementary operations from algebra, trigonometry, calculus, and differential equations. With a minimum of prerequisites this book is accessible to and useful for students of mathematics, computer science, and other technical fields. The book contains a CD with the full, searchable text and implementations of all algorithms in the Maple, Mathematica, and MuPad programming languages.

This review is from: Computer Algebra and Symbolic Computation: Elementary Algorithms (Hardcover)

Excellent book covering the basics of building your own computer algebra system, together with its partner text: "Computer Algebra and Symbolic Computation: Mathematical Methods". The author presents the mathematical fundamentals, practical challenges, formulaic solutions, suggested implementations, and examples in a few programming languages appropriate for someone building their own CAS from scratch in very clear prose. The author makes extensive further reading recommendations for each topic.

At each stage of the development, the author presents the motivation for each feature of the CAS along with formal basics of the math behind the techniques. The author presents the basic practical challenges faced by the computer and algorithms in working with the math. Together, these make the text appropriate for both those with math experience moving into programming, and programmers moving towards math. The author lists step-by-step techniques from a mathematician's point of view for solving the problems, and then continues to give algorithm listings in an easily-read "Math Pseudo Language", complete with flow charts explaining the more complex algorithms. A formal computational complexity analysis of the algorithms is not included.

The author's examples are provided in Mathematica, MuPad, and Maple, but not in C-like languages. The examples, however, are function/structure-based, and are thus clear enough as to be immediately extensible to the reader's language of choice. For an engineer, the examples amount to a practical recipe. The book also contains a CD with the examples & the text of the book as a .pdf. However, this .pdf is only directly accessible to Windows users. Mac users will need to use Windows to run the included Windows app which can access the .pdf and then save it into another .pdf file to use on their Mac. (I've never seen anything like this before! The .pdf files on the CD show up as "Zero KB Symbolic links" on the Mac which don't resolve unless opened in Windows! In the end, I was able to get the .pdf onto my iPhone so I can easily carry the e-book with me when traveling.)

The author provides insight into both the mathematical and computational limitations of the algorithms, the problems caused by the limitations, and frequently gives examples for recognizing the limitations or working around them.

Finally, the author provides extensive references for further reading for details on particular topics.

In all cases, the author's mastery of English prose makes the information easily accessible, which is not at all the case with some other CAS books I've wasted money on... Speaking of price, considering the extreme niche market and the exquisiteness of the text, the combined price of the two books was worth it.

To help the potential customer (as a preview is not available), this book is the one of the two books (which can be effectively read in any order), and covers the basics of CAS's, the included Math Pseudo Language (MPL), defining mathematical expressions as data and functions, solving first order ordinary differential equations, recursion, basic indefinite symbolic integration algorithms, manipulation of general polynomial and rational expressions, and transforming exponential and trigonometric expressions with expansions and contractions.

It's possible I may one day find a more extensive text with more advanced techniques, but the two texts provide a foundation for building my own CAS.

5.0 out of 5 stars A scholarly text and a seminal reference, March 6, 2003

By 

Midwest Book Review (Oregon, WI USA) - See all my reviews

This review is from: Computer Algebra and Symbolic Computation: Elementary Algorithms (Hardcover)

Computer Algebra And Symbolic Computation: Elementary Algorithms by mathematician and computer expert Joel S. Cohen is a scholarly text and a seminal reference to the science of computer algebra and programming elementary mathematical expressions both iteratively and recursively. Structures of polynomials and rational expressions, exponential and trigonometric transformations are also covered in this solid teaching tool packed with exercises and sample code. An accompanying CD provides the student with the entire print text, useful internet hyperlinks, and complete algorithms. Highly recommended.
