matlab多因子选股模型，计算每只股票的得分，根据股票的得分划分为n个区间(matlab multi-factor stock selection model to calculate the score for each stock, based on the stock s score is divided into n intervals)

适合初学者学习的matlab手册，并且有常用的例程(Suitable for beginners to learn matlab manuals, and a commonly used routine)

说明：  dynamic time warping source code

本代码是利用dwt小波分析，实现了对音频加入灰度水印的源代码，可直接运行，生成两个音乐文件，一个是嵌入声音后的，另外一个是噪声文件。(This code is the use of wavelet analysis dwt, the realization of audio into grayscale watermark source code can be run directly, generates two music files, one after the embedded voice, the other is the noise file.)

对实际测得坐标实现圆拟合，前提是几何形状近似圆(The actual measure coordinates are fit to a circle, provided that that geometry approximates the circle)

说明：  武汉理工大学程磊编写的AR模型的Burg算法的matlab程序，有用(Wuhan Polytechnic University Hai prepared by the AR model Burg algorithm Matlab procedures useful)
