有向图中求最大流的一种方法：feasible_match求最大流(Directed graph and maximum flow of a kind of methods: feasible_match for maximum flow)

书后习题：信道均衡的简单仿真。适合入门的同学使用。(Book exercises: a simple simulation of channel equalization. Students for entry-use.)

说明：  JPDA算法,仿真MATLAB 大家仔细学习啊(JPDA algorithm, MATLAB simulation we carefully study ah)

说明：  AWGN信道下，fqpsk 调制的MAP检测 (under awgn channel,MAP demodulation for FQPSK modulation)

说明：  利用matlab编写的基于计算机声卡的虚拟仪器，含信号发生器、示波器和频率计，并利用matlab中guide可视化编程实现了界面操作。(Matlab prepared using computer sound card based virtual instrument, with the signal generator, oscilloscope and frequency meter, and use visual guide matlab programming in the interface operation.)

对一幅图像的频谱进行频率位移，移到窗口中央，并显示出频率变换后的频谱图(The frequency spectrum of the image frequency shift, to move the central window, and shows the spectrum after the frequency conversion)

openExcel :用Matlab打开启动Excel服务器，并返回Excel活动页的句柄H jitt : 利用传入的周期向量，计算频率抖动 norma : 把计算得到的向量平均采样为30个点 interest ： 复利计算方法 myvad : 通常vad算法只能得到汉语普通话一声、二声和四声的语音，对于三声，中间因为有嘎裂，就是突然基频变得很低并且不规则，vad算法把一个音节往往切分为两个音节，myvad解决普通话三声的问题 (Open Excel sever by Matlab, and returen a handle of Excel active sheet)

matlab环境下常微分方程的结算方法，主要介绍数值算法。(proportional navigation trajectory )
