Sinopsis

MATLAB is a software program that is widely available for digital computers at a large number of universities and on a large variety of machines. As will be noted in this text, we will make extensive use of it. The two and three dimensional plotting capabilities will be exploited throughout this text since a picture or a graph can usually aid in the physical interpretation of an equation. Herein, we will briefly present an introduction of several germane features of this program that will be useful for electromagnetic theory. Various functions such as trig functions appear in a MATLAB library that can be easily called and used. The user can customize and add to this list by writing a program in a ".m" (dot m) file. Several MATLAB figures will be included throughout this text. In addition, the files that have been used to create the figures in the text are available at the following web site: [http://www.scitechpub.com/]. These programs will be characterized with the names: “example_103” and “figure_103” to indicate the third example and the third figure in chapter 1. The example and figure captions are identified in the book with the superscript notation MATLAB. Matrix operations will not be examined since their application will receive minimal attention in this text. We assume that the reader is able to call MATLAB and have the familiar MATLAB prompt ">>" appear on the screen. Typing the words, "help topic" after the prompt brings on-screen help to the user.
