非线性量化。读取wav文件，用2到12比特数量化。抽样频率8KHz。()

ROC曲线~在信号检测理论中,接收者操作特征(receiver operating characteristic),或者叫ROC曲线是一种对于灵敏度进行描述的功能图像.ROC曲线可以通过描述真阳性率(TPR)和假阳性率(FPR)来实现.由于是通过比较两个操作特征(TPR和FPR)作为标准,ROC曲线也叫做相关操作特征曲线(ROC curve ~ in signal detection theory, the receiver operating characteristics (receiver operating characteristic), or called the ROC curve is a function that describes the sensitivity of the image. ROC curve can describe the true positive rate (TPR) and false positive rate ( FPR) to achieve. because it is by comparing the two operating characteristics (TPR and FPR) as a standard, ROC curve is also called the relevant operating characteristic curve)

说明：  基于MATLAB下以LMI工具箱为基础的控制系统设计(Based on the LMI toolbox under MATLAB-based Control System Design)

该代码实现了在鼠标框定区域内的Harris Corner的检测(This code deals with the detecting of harris corners with matlab)

关于OFDMA的介绍，初学者很容易理解。且有本人阅读时做下的一些笔记，愿对大家有用。(On OFDMA in the introduction, it is easy for beginners to understand. I read and have done at some of the notes, would like for all of us.)

说明：  可方便地实现聚类分析,MATLAB版的,多多珍惜啊(Can easily realize cluster analysis, MATLAB version, a lot of Value ah)

马尔科夫链蒙特卡洛方法的一个例子，对初学者有用(An example of Markov chain Monte Carlo method, useful for beginners)
