These can be reduced dramatically thanks to our systems for on-line condition monitoring and automatic lubrication. We help make it more economical to create cleaner, cheaper energy out of thin air. By sharing our experience, expertise, and creativity, industries can boost performance beyond expectations.

Valentine and the staff at Butterworth-Heinemann, Elsevier would like to dedicate this book to the memory of Brian Hahn, who wrote the first edition in while he was an Associate Professor in the Department of Mathematics and Applied Mathematics, University of Cape Town, South Africa.

His first post as Lecturer was at the University of the Witwaterstrand, Johannesburg.

He was promoted to Senior Lecturer in Brian served as Head of Department for five years. He was a loved and respected teacher whose expertise in modeling and computing translated so well into the first year Applied Mathematics courses.

He was the author of more than ten books on programming languages. We trust that the third edition of this book will continue to help students understand and exploit the full power of MATLAB both as a mathematical tool and as a programming language.

This page intentionally left blank Preface to the third edition The main purpose in planning a third edition of this book was to upgrade it to cover the latest version of MATLAB Version 7. The other purpose was to maintain the objectives of the late Brian D.

Hahn as stated in the prefaces of the first and second edition. In his prefaces to the first and second edition, he pointed out the following: This book presents the MATLAB computer programming system as a problemsolving tool for scientists and engineers who have no prior knowledge of computer programming.

It is based on a teach-yourself approach; readers are frequently invited to experiment for themselves in order to discover how particular constructs work. The text was originally written as a companion to a hands-on course at the University of Cape Town. Most of the students taking the course had little or no computing experience and came from disadvantaged backgrounds.

Again, unlike most comparable books, this text does not assume any knowledge of matrices on the part of the reader; in fact the concept is developed gradually, as the context requires it.

Since the book is written primarily for scientists and engineers, some of the examples of necessity involve some first-year university mathematics, particularly in the last chapter.

However, these examples are self-contained, and omitting them will not detract from the development of your programming skills.

For the more patient, it also offers conventional programming by means of script files. This book makes good use of both modes. On the one hand, it encourages the use of cut-andpaste techniques to take full advantage of the interactive Windows environment, Preface while on the other hand also stressing programming principles and algorithm development, with the help of structure plans.

Constructs, such as for and if, are not therefore always introduced in their most general form initially, as is common in many texts, but rather more gradually in the most natural places throughout the book. On the other hand, many texts present these constructs somewhat superficially; this book attempts to discuss them thoroughly.

For the curious, there are helpful syntax and function quick references in the appendices. The text warns the user of these wherever possible. The fundamentals of MATLAB are motivated throughout with many examples, from a number of different scientific and engineering areas, such as simulation, population modeling, and numerical methods, as well as from business and everyday life.

Beginners, as well as experienced programmers wishing to learn MATLAB as an additional language, will therefore find plenty of interest in the book. Emphasis is also placed on programming style throughout the book—writing clear and readable code.

Complete solutions to many of the exercises appear in an appendix. There is a comprehensive and instructive index. For the second edition, in working my way through Version 6, I found so many interesting new features for example, GUIs that I was unable to resist incorporating most of them into the text.

Consequently I decided to split the book into two parts. In this edition I have attempted to retain the style and approach of the first edition: Several of the chapters from the previous editions, which xviii Preface feature the essential elements of MATLAB, have been brought together to form Part 1.

In addition, I have added two new chapters. These are Chapters 3 and Chapter 3 describes a structured step-by-step method to achieve top-down design and algorithm development.I'm using importdata to strip off a header and import a file into my workspace.
