(MATLAB (short for Matrix Laboratory) is a professional computer program for engineering science matrix math. But in later years, it has gradually developed into an extremely flexible computing system for solving a variety of important technical issues. MATLAB MATLAB language program execution, and provides a very wide range of predefined libraries, so that makes work easy and efficient technology. In solving engineering problems, MATLAB than any other computer language (including FORTAN and C) are simple and efficient. This book describes the MATLAB language, and to show you how to use it to solve the classic technical problems.)
