大家好：

附件是MATLAB Demystified.pdf的RAR压缩文件，由McGraw-Hill公司2007年出版。McGraw-Hill出版书非常注重实用性，这个特点在其Demystified系列得到很好的体现，本书也不例外。

作者简介如下：
David McMahon, Ph.D., is a physicist and researcher at Sandia National Laboratories. He is the author of Linear Algebra Demystified, Quantum Mechanics Demystified, Relativity Demystified, Signals and Systems Demystified, and Statics and Dynamics Demystified.

书的前言如下：
MATLAB is one of the most widely used computational tools in science and engineering. No matter what your background—be it physics, chemistry, math, or engineering—it would behoove you to at least learn the basics of this powerful tool.

There are three good reasons to learn a computational mathematics tool. The first is that it serves as a background check for work you might be doing by hand. If you are a student, it’s nice to have a back up that you can use to check your answers. I advise that you don’t become co-dependent on a computational tool or trust it as though it were an Oracle. Do your work by hand when requested by your professors and just use MATLAB or any other tool to check your work to make sure it’s correct.

The second reason is having a tool like MATLAB is priceless for generating plots and for doing numerical methods. Instead of having to go through a tedious process of plotting something by hand you can just have MATLAB generate any nice plot you desire.

Thirdly, the bottom line is that at some point in your career you will have to use a computational mathematics tool. If you’re a professor doing theoretical work, at one point or another you are going to be working on a project where analytical solutions are not possible. If you work in industry or in a national lab, chances are the work you’re doing can’t be done by hand and will require a numerical solution. MATLAB is widely used in universities, in national laboratories and at private companies. Knowing MATLAB will definitely be a plus on your resume.

Now a word about this particular book. This book is aimed squarely at the MATLAB beginner. The purpose is not to wow experts with complicated solutions built with MATLAB. Rather, the purpose of this book is to introduce a person new to MATLAB to the world of computational mathematics. The approach taken here is to set about learning how to use MATLAB to do some basic things-plot functions, solve algebraic equations, compute integrals and solve differential equations for example. So the examples we present in this book are going to be simple and aimed at the novice. If you have never touched MATLAB before or are having lot’s of trouble with it, this book will help you build a basic skill set that can be used to master it. The book is a stepping stone to mastery and nothing more.

我很喜欢Demystified系列书籍，浅显易懂，是实用的好帮手。希望大家喜欢和支持！
