Basics of MATLAB and Beyond

Andrew Knight

MATLAB The tremendously popular computation, numerical analysis, signal processing, data analysis, and graphical software package-allows virtually every scientist and engineer to make better and faster progress. As MATLAB's world-wide sales approach a half-million with an estimated four million users, it becomes a near necessity that professionals and students have a level of competence in its use. Until now, however, there has been no book that quickly and effectively introduces MATLAB's capabilities to new users and assists those with more experience down the path toward increasingly sophisticated work.
Basics of MATLAB and Beyond is just such a book. Its hands-on, tutorial approach gently takes new users by the hand and leads them to competence in all the fundamentals of MATLAB. Then, with equal effectiveness, it covers the advanced topics that lead to full, creative exploitation of MATLAB's awesome power. With this book, readers will:

Solve more problems with MATLAB-and solve them faster

Create clearer, more beautiful graphics with control over every detail

Create their own MATLAB code

Share their work by exporting data and graphics to other applications

Develop graphical user interfaces
Based on the latest 5.x release, Basics of MATLAB and Beyond supplies both novice and experienced users the tools they need to gain proficiency, increase productivity, and ultimately have more fun with MATLAB.

Notă biografică

The author completed a Ph.D. in plasma physics at the Flinders University of South Australia in the days before MATLAB. Consequently, he knows how much time can be saved when you don’t have to write your own matrix inversion or polynomial evaluation routines in FORTRAN. His first exposure to MATLAB was at the Centre for Plasma Physics Research at the Swiss Federal Institute of Technology (Ecole Polytechnique Fédérale) in Lausanne, Switzerland, where he continued his research in plasma physics. On his return to Australia to take up a position with the Maritime Operations Division of the Defence Science and Technology Organisation, he was given responsibility for research in the flow noise problem of towed sonar arrays. His current research interests include sonar signal processing and information displays. He has been largely responsible for the growth in the use of MATLAB in his division, and has conducted training courses in MATLAB.
