在试验中编写程序实现了K均值聚类算法,K均值聚类的原理是：在训练样本中找到C个聚类中心，每个聚类中心代表一个类的中心。然后将样本归类到与其最近的聚类中心的那一类。 C的选择是通过先验知识或经验选取的。聚类中心是通过算法迭代求得的。(In the test preparation process to achieve a K means clustering algorithm, K means clustering principle is: in the training samples to find C a cluster center, each cluster center represents a kind of center. Then the samples are classified to the nearest cluster center with the type. C' s choice is a priori knowledge or experience through the selected. Cluster center is obtained through the iterative algorithm.)

说明：  1、指标信号，仅当参考；理解理念，才更重要！指标中大阳支撑的理念，请大家适当参考；其余提示信号，均可只当戏玩，不可生搬硬套！ 2、【烧香拜佛】指标极其简单，不可单独使用，请结合盘面热点、板块龙头等情况，综合考虑目标的机会。 3、该指标对于进入主升浪、台阶式上涨的目标，最为有效！ 下面给出大智慧L2、飞狐、通达信三种常用软件的版本源码，请需要的朋友适当参考。　(1, indicator signal, only when the reference understand the concept, it is more important! Indicators support the idea of the sun, please refer to the appropriate the remaining prompts signal, can only play when the play, not rote! 2】 【pray to Buddha indicator is extremely simple, is not alone, please combine disk hot plate leading, etc., considering the target opportunity. 3, the indicator for access to the main upward move, stepped up the goal, the most effective! Here are great wisdom L2, flying fox, accessible version of the letter are three commonly used software source code, make a friend in need the appropriate reference.)

本函数用于生成自然数环形矩阵，从里到外是0>n.编写者中北大学09级学生闫**。(This function is used to generate a circular matrix of natural numbers, 0> n from the inside to out. Yan** 09 North University students is the writers has full copyright. )

该算法是根据自适应差分脉冲编码调制原理编写的算法，该算法利用了语音信号样点间的相关性，并针对语音信号的非平稳特点，使用了自适应预测(The algorithm is based on principles of adaptive differential pulse code modulation written algorithm, which samples the voice signal using the correlation between, and for non-stationary characteristics of speech signal using an adaptive prediction)
