说明：  本程序是完成网络的评价路径长度和聚类系数的计算。(This program is to calculate the average path length and clustering coeffient of a network.)

说明：  平面用cohesive单元模拟仿真裂纹扩展和结构失效，裂纹扩展(Plane simulation of crack growth and structure failure, crack growth with cohesive element)

说明：  这是一个机器人轨迹跟踪控制的程序，应用的控制算法为滑模控制。(This is a robot trajectory tracking control program, the application of the control algorithm for sliding mode control.)

本Matlab程序对需要高速穿越大气层的返回舱进行了纵向三自由度的模拟计算，只需输入如下基本参数，初始速度，再入高度，再入角。程序中有比较详细的说明。大气模型采用了真实的1976年美国标准大气模型，内附计算标准大气模型的Matlab程序，只需输入高度和高度间隔即可求出详细的参数值。(The Matlab program calculates the longitudinal three degrees of freedom of a reentry module that requires high speed passage through the atmosphere. Only basic parameters such as initial velocity, reentry height and reentry angle are entered. There are more detailed instructions in the program. The atmospheric model uses the real 1976 American Standard atmosphere model, which contains the Matlab program for calculating the standard atmospheric model. Only the input height and height interval can be used to find the detailed parameter values.)

说明：  本模型采用abaqus自带的connector连接单元建模，实现了钉节点的模拟(In this model, the connector unit of ABAQUS is used to simulate the nail node)

基于bpa的IEEE39节点算例，包含暂态数据和稳态数据(Example of IEEE39 node based on BPA)

说明：  采用simulink搭建IEEE标准33节点仿真模型及.m程序(IEEE standard 33 node simulation model)

说明：  利用BP神经网络实现对民族，古筝，摇滚，流行四类音乐的有效分类。matlab实现，提供数据和详细代码，有解释！(The BP neural network is used to realize the effective classification of four kinds of music: nationality, zither, rock and roll, and popular music. Matlab implementation, provide data and detailed code, there are explanations!)

说明：  质心定位算法实现精度要求低的简单定位，加权质心定位比质心定位定位精度更高一些。(Centroid localization algorithm achieves simple positioning with low accuracy requirement, and weighted centroid localization is more accurate than centroid localization.)
