信号功率谱分析，有各种方法，在此一一编写，方法一(Signal power spectrum analysis, there are various methods, in which 11 the preparation of, method 1)

knn 方法为k均值聚类用于数据点的分类(KNN method for k-means clustering for the classification of data points)

说明：  matlabBFGS程序 呵呵 呵额呵呵呵呵呵呵额(procedures matlabBFGS呵呵呵呵呵呵呵呵呵the amount of the amount of)

RSSI网络边界节点定位问题程序，有一定的参考价值(edge point location using rssi)

采用身高和体重数据作为特征，分别假设二者相关或不相关，在正态分布假设下估计概率密度，建立最小错误率Bayes分类器，写出得到的决策规则，将该分类器应用到训练/测试样本，考察训练/测试错误情况。(The use of height and weight data as the characteristics of the assumption that the two were related or not related to the normal distribution probability density is estimated under the assumption that the establishment of Bayes minimum error rate classifier, the decision-making rules have been written, the classifier is applied to training/test samples to study the training/testing error conditions.)

对正交频分复用中的信号发射利用matlab程序进行了仿真(On orthogonal frequency division multiplexing signal transmission in the use of process simulation matlab)

matlab编写程序过程当中，经常遇到忘记或者不知道代码指令，这个目录可以方便查询代码指令(matlab programming process, frequently encountered forget or do not know the code instructions, this directory can be easily query code instructions)

说明：  提供两个点坐标，可以利用本程序，计算两点距离，简单好用。(Coordinates of two points, you can use this procedure to calculate the distance to two points, easy-to-use.)

先去取两区四机系统的潮流，然后通过设置求取不同情况的下的暂态程序，并得出波形(To go to take the trend of the two four-machine system, and then strike a transient program under different circumstances, and draw the waveform by setting)

用友U852数据字典，供二次开发和报表查询使用(UF U852 data dictionary for the second development and use of report queries)
