图创建一个放大框，当一个按钮被按下时，根据鼠标的位置。按“+”/“ - ”，而按下按钮来增加/减少放大。按 > / < ，而按下按钮来增加/减少箱尺寸。 按住Ctrl键的同时单击离开放大图。(Figure creates a magnification box when under the mouse position when a button is pressed. Press + / - while button pressed to increase/decrease magnification. Press > / < while button pressed to increase/decrease box size. Hold Ctrl while clicking to leave magnification on figure.)

内容完整且每章相对独立；是一本简明的MATLAB参考书，既适用于初学者，也适用于高级MATLAB用户。对MATLAB与FORTRAN、C等语言结合的描述更是所有MATLAB书籍中少有的一大特色。(The contents of each chapter is relatively complete and independent it is a simple MATLAB reference books, both for beginners, but also to high-level MATLAB users. Of MATLAB and FORTRAN, C and other languages with a description of all MATLAB books is a major feature of the few.)

此代码描述的是正弦函数的频谱图,其采样点不同,频谱图的差别(This code is a sine function described in the frequency spectrum, the sampling point is different from the difference spectrum)
