说明：  该程序给出了cohesive单元的刚度矩阵及其在有限元程序中的实现方法。(This program gives the stiffness matrix of the cohesive element and its realization method in the finite element program.)

说明：  k均值聚类+matlab 有详细的注释和图片(failed to translate)

实现通信原理上的PCM（脉冲编码调制）调制与解调等 功能(MATLAB PCM)

说明：  同样是用matlab编写的实现支持向量机的源代码(using Matlab is also prepared to achieve SVM source code)

说明：  本资料系统讲解了随机信号的基础知识，对于以后信号处理的研究有一定的借鉴性。(The information system to explain the basics of random signals, signal processing for future research have certain reference.)

线性递减pso程序代码，使用时更换目标函数即可(Linear decreasing pso code, replace the objective function can be used)
