谱聚类的目的便是要找到一种合理的分割图的方法，使得分割后形成若干个子图，连接不同子图的边的权重（相似度）尽可能低，同子图内的边的权重（相似度）尽可能高(The purpose of spectral clustering is to find a reasonable method of segmentation graphs, so that several subgraphs are formed after segmentation, and the weights (similarities) of the edges connecting different subgraphs are as low as possible, and the weights of the edges in the same subgraph are as low as possible. (similarity) as high as possible)

说明：  用python语言实现二级希尔密码的加解密(Python implements two-level Hill encryption and decryption)

说明：  给出任意弧长，求计算该弧半径。输入弧长的高和两端直线长度，就可以得出半径(Arbitrary Arc for Radius)

本文给出使用Python做小波包特征提取的一个实例，并附有MATLAB编写的实现源码。 数据来源：自己采集得到的模拟电路故障响应数据，存在SumData文件夹中，其中文件夹共有9个excel文件，每一个excel文件存的是某种故障状态下采集得到的100组故障响应数据。(In this paper, an example of using Python to extract the features of wavelet packet is given, and the source code written by MATLAB is attached. Data Source: The fault response data of analog circuits collected by ourselves are stored in the SumData folder. There are nine Excel files in the folder. Each excel file contains 100 sets of fault response data collected under some fault condition.)
