MATLAB 是科学与工程上其中一个非常广泛使用的计算工具，不管你的背景是什么—
—物理、化学、数学还是工程学——它都能适宜你。学习一款数学计算工具有三个好处：第
一，如果你是手工完成计算的，那么它就像一个后台检查工具。假如你是学生，有一个工具
可以检查你的答案总是好的。我并不是说你要过份依赖某种计算工具，好像它就是神谕一样。
如果你的教授要求你手工完成工作，之后你就可以使用 MATLAB 或其它计算工具来检验你
的工作是否正确。(MATLAB is one of the most widely used computing tools in science and engineering, no matter what your background is-
Physics, chemistry, math, or engineering -- it fits you. There are three advantages to learning a mathematical computing tool
First, if you do the calculations manually, then it's like a background check tool. If you are a student, you have a tool
It's always good to check your answers. I'm not saying you're going to rely too much on a computing tool as if it were an oracle.
If your professor asks you to do the work by hand, then you can use MATLAB or other computing tools to test you
Is the work correct?.)
