Summary

MATLAB (short for Matrix Laboratory) is a software tool used widely in engineering curriculum that provides high-performance numerical computational, graphical, and animation capabilities. Many of OUP's engineering titles, including Lathi's Modern Digital and Analog Communications, 4e, the forthcoming Uicker, Pennock and Shigley's Theory of Machines and Mechanisms, 4e, and Sadiku's Elements of Electromagnetics, 5e, incorporate MATLAB codes into the homework problems and chapter examples. The new edition brings the book up to date with MATLAB version 2009a. This includes updating commands, examples, figure, and graphs. Chapter 8 also underwent a complete revamp to address the restructure of symbolic computation in the new version of MATLAB. The author is also taking this opportunity to add additional examples and new topics, including nested functions and PDEs. The book is supplemental in nature and is essentially an introductory user's guide, and is used in a variety of different engineering and science courses.
