It began as a snapshot of the content of a Georgia Tech course that introduces engineers to computing. However, it has been extensively enhanced to meet the needs of a wider audience of students and educators who want to understand programming for other reasons. In this book, to understand computing, we use the basic syntax and capabilities of MATLAB, a user-friendly language that is emerging as one of the most popular computing languages in engineering Fully updated to comply with MATLAB 2008, Engineering Computation with MATLAB, Second Edition, introduces computing to students with no programming experience, David Smith places programming fundamentals into the context of MATLAB 2008, employing hands-on exercises, examples from the engineering industry, and a variety of core tools to increase problem-solving capability and proficiency.
