不错的源代码，喜欢matlab实验的朋友可以下载下来看看：） --模拟小球下落(Good source code, like matlab experiment to see if a friend can download it:) simulation of the fate of small ball)

说明：  通过不同大小的窗口移动，计算每个窗口内地形剖面数据的均方根值，得到的数据在双对数图中拟合直线可求得分维数(move the windows of different size and calculate the rms of the data in the window.Then using the resultant data to plot,so that the fractal dimension can be gotten.)

讲述了现在机械故障诊断中用到的常用时频分析方法，如短时fft 魏格纳维尔分布 小波变换 HHT等，里面含有例子和详细说明，对初学者帮助很大。(Tells the now commonly used in mechanical fault diagnosis frequency analysis methods, such as short-time wavelet transform fft Wigner distribution HHT Louisville, etc., which contains examples and detailed instructions, very helpful for beginners.)

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)

基于matlab的TSp问题处理，能直接运行(TSp problem matlab-based processing can be run directly)

2发1收天线和2发2收天线仿真，误码率，AWGN信道个SISO瑞利衰落信道(1 2 receive antenna and 2 2 receive antenna)

image polar to convert an image from Matrice to polar conrdinate, its about 5 functions that works toguether

视频水印，在每一帧视频帧上嵌入水印，不可见性良好(video waterMarking,embed the watermark on each frame of video,invisibility is mediocre)

说明：  FIR FILTER IMPLEMENTATION

基于Matlab的心理声学模型程序，喜欢的可以研究研究 (Psychoacoustic model based on Matlab program, like research can be studied)
