This book is essentially a supplementary manual to MATLAB, Simulink and Control Toolbox and is aimed at both undergraduate and graduate students and to academic and industrial researchers who work with dynamic systems and numerical problems.The distinguishing feature of the volume is its high number of worked examples. These allow the reader to proceed from the basic MATLAB commands up to the more sophisticated Control System Toolbox procedures and to the optimized SIMULINK scheme avoiding a boring and useless list of functions.The material begins assuming no familarity with MATLAB - Chapter 1 explains how to insert data from keyboard and external files. However, advanced techniques are presented throughout the book in highlighted paragraphs.
