此函数为matlab函数，可以用来绘制出任意函数的包迹线。(Finds the envelope of an arbitrary function)

This MATLAB exercise designs and implements a pitch period detector based on detecting and tracking peaks in the autocorrelation of the LPC error signal during regions of voiced speech. The pitch detection procedure is called the SIFT (Simple Inverse Filtering Tracking) method. The SIFT pitch period detector uses a secondary autocorrelation peak in order to detect and correct pitch period detection errors due to effects such as pitch period doubling and related phenomena.

说明：  longge-kuta法实现，需要下载的请看看哦，绝对实用~~~~(longge-kuta method to achieve, you need to download the See Kane, absolutely practical ~ ~ ~ ~)

Signal Detection and Estimation 关于信号检测与估计的一本英文电子书，本书首先介绍了一些信号的随机过程，然后详细地介绍了一些信号检测和估计的方法。很好的一本外文书，大家一起分享。(Signal Detection and Estimation。This book is primarily designed for the study of statistical signal detection andparameter estimation. In the first,it present concepts on probability and random variables. Then,it present Statistical Decision Theory，Parameter Estimation.It is really a good book,share with all of you.)

说明：  实现的串口通信；的MATLAB与C 在MATLAB与C数据交换中有用(Achieve serial communication the MATLAB and C in MATLAB and C useful for data exchange)

我从这里下载一个MATLAB文件来计算激光的模式，拉盖尔-高斯模式，但它不能正常工作。所以我说我自己的函数。这是很简单的功能，我希望它是有效的以及。我用它和后结果我得到了。(i download one matlab file from here to calculate the modes in laser, Laguerre-Gauss modes but it was not working properly. So i wrote my own function. It is pretty simple function, i hope it is efficient as well. i used it and post the result i got.)

自己编写的平坦因子理论以及信息熵的程序，可用于学习和交流(I have written a flat factor theory, and entropy procedure can be used for learning and communication)

对雷达系统仿真和雷达显示出来器进行了简要综述，，详细介绍了雷达显示出来器仿真思想及其实现方法。 (Details out is a brief overview of the radar system simulation and radar display, radar display out Simulation thought and its implementation method.)

附件中的pdf文件是韩国作者08年在Automatica上发表的文章。本代码给出了文章中定理1的线性矩阵不等式的求解程序，通过给定不同的a来求解最大的b,进而得到界定时滞系统的最小的椭圆。(Attached pdf file of 2008 in South Korea articles published in Automatica. This code is given in Theorem 1 article LMI solver through a given different to solve the biggest b, then get the minimum of delay systems defined ellipse.)
