  • In this chapter, we will introduce you to the tools you need in order to begin using MATLAB effectively. These include the following: some relevant information on computer platforms and software; installation protocols; how to launch MATLAB, enter commands and use online help; a roster of MATLAB’s various windows; and finally, how to exit the program. We know you are anxious to get started using MATLAB, so we will keep this chapter brief. After you complete it, you can go immediately to Chapter 2 to find concrete and simple instructions for using MATLAB to do mathematics.

  • MATLAB®, developed by The MathWorks, Inc., integrates computation, visualization, and programming in a flexible, open environment. It offers engineers, scientists, and mathematicians an intuitive language for expressing problems and their solutions mathematically and graphically. Complex numeric and symbolic problems can be solved in a fraction of the time required with a programming language such as C, Fortran, or Java.

  • A graphical user interface (GUI) is a graphical display in one or more windows containing controls, called components, that enable a user to perform interactive tasks. The user of the GUI does not have to create a script or type commands at the command line to accomplish the tasks. Unlike coding programs to accomplish tasks, the user of a GUI need notgraphical display the details of how the tasks are performed.

  • Matlab is a software package that lets you do mathematics and computation, analyse data, develop algorithms, do simulation and modelling, and produce graphical displays and graphical user interfaces. To run matlab on a PC double-click on the matlab icon. To run matlab on a unix system, type matlab at the prompt. You get matlab to do things for you by typing in commands. matlab prompts you with two greater-than signs () when it is ready to accept a command from you. To end a matlab session type quit or exit at the matlab prompt....

  • Kermit Sigmon, author of the MATLAB® Primer, passed away in January 1997. Kermit was a friend, colleague, and fellow avid bicyclist (although I’m a mere 10-mile-aday commuter) with whom I shared an appreciation for the contribution that MATLAB has made to the mathematics, engineering, and scientific community. MATLAB is a powerful tool, and my hope is that in revising our book for MATLAB 7.0, you will be able to learn how to apply it to solving your own challenging problems in mathematics, science, and engineering....

  • Two of the most important functions for signal processing are not in the Signal Processing Toolbox at all, but are built-in MATLAB functions: • filter applies a digital filter to a data sequence. • fft calculates the discrete Fourier transform of a sequence. The operations these functions perform are the main computational workhorses of classical signal processing. Both are described in this chapter.

  • Each function in MATLAB contains a set of variables specific to that function. Even in the same .m file, you don’t have (direct) access to variables created in other functions within the file. Global variables give you the ability to create/change a variable in one function and have that updated variable accessible elsewhere. This post will discuss two methods for handling (no pun intended) global variables, one of which is perfectly integrated into Graphical User Interfaces (GUIs).
