用matlab实现的可以发送email的程序，该程序有m文件实现和函数实现两种形式。(Using matlab to achieve can send email program, the program has m-file and function implementation and realization of two forms.)

说明：  迭代法 迭代式阈值选取的基本思路是:首先根据图像中物体的灰度分布情况， 选取一个近似阈值作为初始阈值(Iterative threshold selected basic idea is: First, the gray-scale distribution of objects in the image, select an approximate threshold as initial threshold)

劳斯稳定性判据的matlab实现。直接运行M文件，按提示输入特征多项式参数，即可进行系统稳定性判别。(The Routh-Hurwitz stability criterion is a necessary (and frequently sufficient) method to establish the stability of a single-input, single-output (SISO), linear time invariant (LTI) control system. More generally, given a polynomial, some calculations using only the coefficients of that polynomial can lead us to the conclusion that it is not stable. in this program you must give your system coefficents and the Routh-Hurwitz table would be shown )

本程序为微波视距信道的仿真，采用三径模式，四抽头仿真模型，以正弦信号为例进行的仿真。()

霍夫变换的源程序，专门用于复杂背景下圆孔的中心定位(Hough transform of the source, specifically for the complex context of the central positioning hole)

基于matlab 的MP3音频播放器。能够实现播放、暂停、停止等基本功能。同时可以绘制波形图。(Matlab-based MP3 audio player. Enables play, pause, stop, and other basic functions. At the same time you can draw waveforms.)

二维方腔流动流函数涡量法.上边界为移动边界，cavity流动，涡量为负值。(Dimensional square cavity flow stream function vorticity law. On boundaries for the moving boundary, cavity flow, vorticity is negative.)
