说明：  本书以单元练习的形式，从MATLAB最基本的问题入手，循序渐进，逐渐过渡到较为复杂的数学问题、信号分析问题、力学问题和电学问题的求解，将MATLAB的学习贯穿在解决不同领域实际问题的过程当中。每一个练习都结合问题，介绍与之相关的MATLAB使用知识。全书50个练习基本上涵盖了MATLAB的主要功能。本书不仅是一本初学者可以用来入门的教程，而且对于专业设计人员来说，也是一本内容翔实、可供借鉴的参考
(In the form of unit practice, this book starts with the most basic problems of MATLAB, gradually transits to the solution of more complex mathematical problems, signal analysis problems, mechanical problems and electrical problems, and runs the learning of MATLAB through the process of solving practical problems in different fields. Each exercise is combined with the problem, and introduces the knowledge of MATLAB. The 50 exercises in the book basically cover the main functions of MATLAB. This book is not only a tutorial for beginners, but also a reference for professional designers)
