emd源程序的工具包，只要编写主程序调用即可，非常经典(emd source toolkit, just write the main program calls can be very classic)

在二维空间里有两个点A=(X1，Y1)和B=(X2，Y2)，如果X1>X2并且Y1>Y2 ，我们认为A优于B，A是这个集合的最大极值点，在给定的二维空间里的N个点的集合S中，找出最大极值点。(In two-dimensional space, there are two points = A = (X1, Y1) and B (X2, Y2), if the X1 and Y1 > X2 > Y2, we think that A is superior to B, A is the biggest extreme value point of the set, in A given set of N points in the two-dimensional space S, find out the most extreme value point.)

S变换的matlab源码，并应用几个信号作为例子来说明怎么使用s变换以及s变换可以用来做些什么事情。s变换是时频分析领域中一个较新的内容，现在在信号处理，地震勘探，语音识别等领域都开始了对它的应用研究，是目前的一个热点。(S transform matlab source, and apply some signal as an example to illustrate how to use s and s transform transform can be used to do things. s transform time-frequency analysis are a relatively new area of content, now in the signal processing, seismic exploration, speech recognition and other areas of the beginning of its applied research, is a hotspot.)

代码是MATLAB环境下基于k-nn算法的分类器对数据iris的分析(under matlab environment based on k-nn classifier for the iris.data)

简单的小程序源代码，matlab的基础，看后有帮助(failed to translate)

2PSK的调制解调过程的仿真及在不同信道下误码率仿真分析(2PSK modem emulation and simulation of BER)

说明：  levy噪声，两个文件，levy是产生levy噪声，另一个是画图(Levy noise, two files, levy is the generation of levy noise, the other is drawing)

说明：  一个完整很不错的OFDM程序，在给出OFDM系统模型的基础上，用MATLAB语言实现了整个系统的计算机仿真并给出参考设计程序(A complete OFDM is very good procedures in OFDM system model is given based on the MATLAB language with a computer simulation of the entire system and gives reference to the design process)

求出多个信号的FFT频率并显示谱图，同时求出多个信号的功率谱并显示谱图(The FFT frequency of multiple signal and display the spectrum diagram, at the same time, the power spectrum of multiple signal and display spectrogram )
