给定高低值计算抛物线sar值，只是初步分析，希望对有兴趣的有所帮助。(Uses technique described on the Parabolic SAR wikipedia page. Candlestick Graph package used to create picture.)

聚类算法，不是分类算法。分类算法是给一个数据，然后判断这个数据属于已分好的类中的具体哪一类。聚类算法是给一大堆原始数据，然后通过算法将其中具有相似特征的数据聚为一类。这里的k-means聚类，是事先给出原始数据所含的类数，然后将含有相似特征的数据聚为一个类中。所有资料中还是Andrew Ng介绍的明白。首先给出原始数据{x1,x2,...,xn}，这些数据没有被标记的。初始化k个随机数据u1,u2,...,uk。这些xn和uk都是向量。根据下面两个公式迭代就能求出最终所有的u,这些u就是最终所有类的中心位置。(Clustering algorithm, not a classification algorithm. Classification algorithm is to give a figure, and then determine the data belonging to a specific class of good which category. Clustering algorithm is to give a lot of raw data, and then through the algorithm which has similar characteristics data together as a class. Here k-means clustering, is given in advance the number of classes contained in the raw data, then the data contain similar characteristics together as a class. All information presented in or Andrew Ng understand. Firstly, raw data {x1, x2, ..., xn}, the data is not labeled. K random initialization data u1, u2, ..., uk. These are the vectors xn and uk. According to the following two formulas can be obtained final iteration all u, u is the ultimate all these classes the center position.)

这是一个matlab关于模型预测控制的例子，主要是一个机械转台的控制仿真，希望对学习模型预测控制的同学有帮助(This is an example matlab on model predictive control is mainly a mechanical turntable control simulation, in the hope of learning model predictive control to help students)

产生m序列的源代码，为5级线性反馈移位寄存器，有兴趣的可以看看(Generate the source code of the m-sequence, five linear feedback shift register, interested can look at)

说明：  关于雷达建模的一本书中很详细的Matlab代码，第3章：连续波和脉冲雷达。(Matlab code about radar system simulation, chapter3: continuous wave and pulsed radar.)

OFDM 技术具有频谱利用率高、成本低等特点，随着人们对通信数据化、宽带化、个人化和移动化的需求，OFDM 技术在固定无线接入领域和移动接入领域将越来越得到广泛的应用(OFDM technology has high spectrum efficiency, low cost, and communication data, broadband, personal and moving the OFDM technology will increasingly be in the field of fixed wireless access and mobile access a wide range of applications)

说明：  《matlab小波分析》的第二章源代码，与书是配套的，挺好的(&quot Matlab wavelet analysis,&quot the source code of the second chapter, with the book are complementary, and quite good)
