MATLAB Programming for Engineers Fifth Edition Edition by Stephen J. Chapman pdf.
MATLAB (short for MATrix LABoratory) is a special-purpose computer program optimized to perform engineering and scientific calculations. It started life as a program designed to perform matrix mathematics, but over the years it has grown into a flexible computing system capable of solving essentially any technical problem.
The MATLAB program implements the MATLAB language and provides a very extensive library of pre-defined functions to make technical programming tasks easier and more efficient. This extremely wide variety of functions makes it much easier to solve technical problems in MATLAB than in other languages such as Fortran or C. This book introduces the MATLAB language as it is implemented in version R2014b, and shows how to use it to solve typical technical problems.
This book teaches MATLAB as a technical programming language showing students how to write clean, efficient, and documented programs. It makes no pretense at being a complete description of all of MATLAB’s hundreds of functions. Instead, it teaches the student how to use MATLAB as a computer language and how to locate any desired function with MATLAB’s extensive on-line help facilities. The first eight chapters of the text are designed to serve as the text for an “Introduction to Programming/Problem Solving” course for freshman engineering students. This material should fit comfortably into a nine-week, three-hour course.
The remaining chapters cover advanced topics such as I/O, Object-Oriented Programming, and Graphical User Interfaces. These chapters may be covered in a longer course or used as a reference by engineering students or practicing engineers who use MATLAB as a part of their coursework or employment.
Features of this Book:
Many features of this book are designed to emphasize the proper way to write reliable MATLAB programs. These features should serve a student well as he or she is first learning MATLAB, but should also be useful to the practitioner on the job. They include:
1. Emphasis on Top-Down Design Methodology The book introduces a top-down design methodology in Chapter 4 and then uses it consistently throughout the rest of the book. This methodology encourages a student to think about the proper design of a program before beginning to code. The book emphasizes the importance of clearly defining the problem to be solved and the required inputs and outputs before any other work is begun. Once the problem is properly defined, the book teaches students to employ stepwise refinement to break tasks down into successively smaller sub-tasks, and to implement the subtasks as separate subroutines or functions. Finally, students are taught the importance of testing at all stages of the process, both unit testing of the component routines and exhaustive testing of the final product.
The formal design process taught by the book may be summarized as follows:
1. Clearly state the problem that you are trying to solve.
2. Define the inputs required by the program and the outputs to be produced by the program.
3. Describe the algorithm that you intend to implement in the program. This step involves top-down design and stepwise decomposition using pseudocode or flow charts.
4. Turn the algorithm into MATLAB statements.
5. Test the MATLAB program. This step includes unit testing of specific functions as well as exhaustive testing of the final program with many different data sets.
2. Emphasis on Functions
The book emphasizes the use of functions to logically decompose tasks into smaller subtasks. It teaches the advantages of functions for data hiding. It also emphasizes the importance of unit testing functions before they are combined into the final program. In addition, students learn about the common mistakes made with functions and how to avoid them.
3. Emphasis on MATLAB Tools
The book teaches the proper use of MATLAB’s built-in tools to make programming and debugging easier. The tools covered include the Editor/ Debugger, Workspace Browser, Help Browser, and GUI design tools.
4. Good Programming Practice Boxes
These boxes highlight good programming practices as they are introduced for the student’s convenience. In addition, the good programming practices introduced in a chapter are summarized at the end of each chapter. An example of a Good Programming Practice Box is shown below.
