平面圆阵波束形成，使用阵列流型向量编写，对于理解波束形成有帮助(Planar circular array beamforming, the use of array-based flow vector preparation, for help understanding beamforming)

PCA algorithm in matlab

利用matlab编写的俄罗斯方块，是matlabGUI设计的很好的实例(a Tetris program compiled with matlab GUI)

轴承故障诊断，经验模态分解，采用切片双谱(Bearing fault diagnosis, empirical mode decomposition, using slices bispectral)

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.)

ccs网页上图像样式处理。内含有两个文件，一个是样式里包含两个按钮风格。(ccs style image processing.)

Five very good books. They are A Novel Method to Analyze Electromagnetic Scattering of Complex Objects, matlab&GUI, Win32 API Reference for HLA, Monte carlo strategy in scientific computation, Data structure and C++ algortihms.

利用matlab算出能流反射率和能流透射率随入射角度的变化曲线(Energy flow is calculated using matlab reflectance and transmittance curves can flow with the incident angle)

设采样频率为1Hz，对于淹没在复高斯白噪声中的信噪比为 的两个复LFM信号，采用子带带宽为0.1Hz的升余弦滤波器，共9个子带滤波器构成的滤波器组，时间窗为窗长为256的矩形窗，进行仿真(based sampling frequency of 1Hz. For drowned in the complex Gaussian white noise to the signal-to-noise ratio of 2 Minute LFM, using sub-band bandwidth of 0.1 Hz or cosine filter, a total of nine sub-band filter a filter group, time window to window to 256 long rectangular window simulation)

简单的均匀加权线阵的仿真，有出方向图，权值与入射信号干扰噪声都无关，直接就是【1，1，1……】(a simple simulation of ULA)
