function Px = per(x,n1,n2) PER Estimate the spectrum of a process using the periodogram ----------- USAGE Px = per(x,n1,n2) The spectrum of a process x is estimated using the periodogram. x : input sequence n1 : starting index, x(n1) n2 : ending index, x(n2) The periodogram is returned in Px using a linear scale. If n1 and n2 are not specified the periodogram of the entire sequence is computed.

说明：  珍藏版，可实现，新K均值聚类算法，分为如下几个步骤： 一、初始化聚类中心 1、根据具体问题，凭经验从样本集中选出C个比较合适的样本作为初始聚类中心。 2、用前C个样本作为初始聚类中心。 3、将全部样本随机地分成C类，计算每类的样本均值，将样本均值作为初始聚类中心。 二、初始聚类 1、按就近原则将样本归入各聚类中心所代表的类中。 2、取一样本，将其归入与其最近的聚类中心的那一类中，重新计算样本均值，更新聚类中心。然后取下一样本，重复操作，直至所有样本归入相应类中。 三、判断聚类是否合理 采用误差平方和准则函数判断聚类是否合理，不合理则修改分类。循环进行判断、修改直至达到算法终止条件。(NewK-means clustering algorithm ，Divided into the following several steps: A, initialize clustering center 1, according to the specific problems, from samples with experience selected C a more appropriate focus the sample as the initial clustering center. 2, with former C a sample as the initial clustering center. 3, will all samples randomly divided into C, calculate the sample mean, each the sample mean as the initial clustering center. Second, initial clustering 1, according to the sample into the nearest principle clustering center represents the class. 2, as this, take the its recent as clustering center of that category, recount the sample mean, update clustering center. And then taking off, as this, repeated operation until all samples into the corresponding class. Three, judge clustering is reasonable Adopt error squares principles function cluster analysis.after clustering whether reasonable, no reasonable criterion revisio)

实现了蓄电池的并网，其中包含了蓄电池模型、四象限变流器模型和控制器模型，控制器控制有功无功，实现蓄电池和交流系统间的功率交换(which contains the battery model, four-quadrant converter model and the controller model, the controller controls the active and reactive power to achieve the battery and AC power exchange between systems.)

这个是用MATLAB编的一个维纳滤波器程序，内涵解释，对初学者会有帮助。(This is a Wiener filter program compiled using MATLAB, the connotation would help explain, for beginners.)
