MATLAB is a computer-based system designed primarily to assist the academic, research and industrial communities in solving complex technical problems. It is one of the leading software packages for carrying out programming and numerical computations. SIMULINK (Simulation and Link) is a tool integrated within MATLAB to facilitate high-tech solutions to various engineering and scientific problems. This book closes the gap between the software package and its users so that they can succeed easily in today's competitive world. It provides the reader with the requisite understanding of these computational and block diagram environments which may further enhance employment opportunities for professionals in science and various engineering streams.
