说明：  主成分分析算法，有大量数据，初学者可以根据数据看程序，并且可以出现图像(Principal component analysis algorithm, there is a large amount of data, beginners can look at program according to the data, and can appear the image)

Use Metropolis procedure to sample from Cauchy density

Matlab Data mining code

这是一个利用维纳滤波方法进行消噪的MATLAB 程序，器效果比谱减法好在没有尖锐的噪声(it is a delete noise program.it is based on matlab)

说明：  各种滤波器包括高斯、维纳、laplace、中值滤波器(Various filters, including Gaussian, Wiener, laplace, median filter)
