Book Description

Publication Date: 6 Nov 2000 | ISBN-10: 1558606793 | ISBN-13: 978-1558606791 | Edition: Har/Cdr
Numerical methods naturally lend themselves to an object-oriented approach. Mathematics builds high- level ideas on top of previously described, simpler ones. Once a property is demonstrated for a given concept, it can be applied to any new concept sharing the same premise as the original one, similar to the ideas of reuse and inheritance in object-oriented (OO) methodology. Few books on numerical methods teach developers much about designing and building good code. Good computing routines are problem-specific. Insight and understanding are what is needed, rather than just recipes and black box routines. Developers need the ability to construct new programs for different applications. "Object-Oriented Implementation of Numerical Methods" reveals a complete OO design methodology in a clear and systematic way. Each method is presented in a consistent format, beginning with a short explanation and following with a description of the general OO architecture for the algorithm. Next, the code implementations are discussed and presented along with real-world examples that the author, an experienced software engineer, has used in a variety of commercial applications. On the enclosed CD-ROM, you'll find files containing tested source code implementations of all the algorithms discussed in the book in both Java and Smalltalk. This includes repository files for VisualAge for Java and VisualAge for Smalltalk under ENVY. It reveals the design methodology behind the code, including design patterns where appropriate, rather than just presenting canned solutions; implements all methods side by side in both Java and Smalltalk. This contrast can significantly enhance your understanding of the nature of OO programming languages; provides a step-by-step pathway to new object-oriented techniques for programmers familiar with using procedural languages such as C or FORTRAN for numerical methods; and, includes a chapter on data mining, a key application of numerical methods.

Amazon Review

Didier Bessett's Object-Oriented Implementation of Numerical Methods offers a wide-ranging set of objects for common numerical algorithms. Written for the math-literate Java and Smalltalk programmer, this volume demonstrates that both languages can be used to tackle common numerical calculations with ease.

This title bridges the gap between pure algorithms and object design. By tackling issues like class design, interfaces, and overcoming floating-point rounding errors in both Java and Smalltalk, the code can be used as is or as a model for your own custom numerical classes.

The range of recipes, or sample numerical classes, all coded in both OOPLs, is rich. For anyone who's taken a few undergraduate math courses (like calculus, linear algebra, or statistics), plenty of the material will be familiar. After presenting some basic algorithm and mathematical principles, the book shows you the code that gets the job done (first in Smalltalk and then in Java). There's no room for demo code that shows how to use all this. The emphasis is on a good cross-section of common numerical calculations. The tour begins with calculus and moves through linear algebra, with plenty of material on matrices. Later sections on statistics cover familiar terms and calculations like linear regression and calculations useful for establishing correlations between one or more independent variables. Sections on data mining examine the mathematical rules for finding patterns in large amounts of data. (There's also a nifty set of classes for implementing genetic algorithms.) Throughout, you get advice on choosing the right algorithm for the job. (There are class diagrams that map out how this class library is organised.)

Of course, it will help to know some of the underlying maths to get the most out of this intelligent and wide-ranging book, but the writing is remarkably clear, and the source code is a model of intelligibility, so even readers who are averse to equations will find Object-Oriented Implementation of Numerical Methods readable. In general, any competent Java or Smalltalk programmer will be able to tap into solid mathematical code by reading it, without having to reinvent the proverbial wheel. --Richard Dragan

Review

"There are few books that show how to build programs of any kind. One common theme is compiler building, and there are shelves full of them. There are few others. It's an area, or a void, that needs filling. this book does a great job of showing how to build numerical analysis programs." - David N. Smith, IBM T J Watson Research Center

For all these reasons, this book tries to convince you that using object-oriented programming for numerical evaluations can exploit the mathematical definitions to maximize code reuse between many different algorithms. Read the first page

5.0 out of 5 stars Excellent book 10 Jan 2001
By Dr. Ivan Tomek - Published on Amazon.com
Format:Hardcover
The author is clearly very familiar with the theory and practice of numerical computations in OO languages. For me, the main contributions of the book are an expert formulation of some of the basic numerical techniques and concepts in OO terms (a subject rarely approached in the numerous existing books on OO technology), and examples that can be followed to implement other NM techniques and concepts.

The inclusion of very readable Smalltalk and Java source code is very useful.

For use in a course, I would like to see the material complemented by exercises.

5.0 out of 5 stars Oh man, is this book neat! 7 Dec 2000
By Lynn B. Hales - Published on Amazon.com
Format:Hardcover|Amazon Verified Purchase
Dr. Besset has written an uncommonly great book where he has given us important tools while teaching object-oriented analysis and design. Having both Smalltalk and Java code included is a gift. As a smalltalker, I greatly appreciate the inclusion of the Smalltalk code. The book is well organized, very readable and provides the basis for individuals to extend the classes provides as well as build applications with the included code. The code also provides solid examples of object-oriented programming style that will aid the newer programmers in developing effective use of both Java and Smalltalk.

5.0 out of 5 stars Reconciling Numerical Methods and Object-Orientation 23 Dec 2000
By ducasse - Published on Amazon.com
Format:Hardcover
I really enjoyed this book because it shows that a high level language such as Smalltalk can efficiently model a complex domain like numerical methods. Besset presents a conceptual framework where the concepts are extended and reused, showing the power of OO programming. I also liked the structure of examples followed by a formal foundation, implementation, and implementation discussion.
