Using examples from mathematics, mechanical and electrical engineering, and control and signal processing, this book provides an introduction to MATLAB and Simulink and examines the advantages and limitations of both. The author demonstrates how to visualize the results of calculations in various kinds of graphical representations, how to write useful script files and functions for solving specific problems, how to avoid disastrous, computational errors, and how to insert calculations and graphs into technical reports produced by either MS Word or LaTeX. Companion software with functions and script files are available online.
