说明：  DE 生物进化算法的matlab实现，一类优化仿生算法(DE biology evolutionary algorithm matlab implementation, a class of bionic optimization algorithm)

本程序实现了语音信号中的信息隐藏，采用DCT和LSB方法。(the information hiding technique is completed with the carrier of voice signal.)

求复杂网络节点之间的最短距离，也叫做测地线，对复杂网络的拓扑性质的分析很重要(Complex networks seeking the shortest distance between nodes, also called geodesic network topological properties of complex analysis is very important)

说明：  通过16个接收水听器组成线列阵，分别给出各个阵元接收信号，可实现 时域、频域等信号到达角判别(A linear array composed of 16 receiving hydrophones can be used to distinguish the angle of arrival of signals.)

可以读取obj格式的文件到matlab空间中，obj格式的文件中，只能包含点和面的信息(Obj file format can be read into matlab space, obj file format, can contain only the information points and surfaces)

说明：  该软件可以隐藏MATLAB编译成可执行文件之后的DOS框！ 非常有用！(The MATLAB software can be hidden after the executable file compiled into the DOS box! Very useful!)

说明：  实验3 离散系统的差分方程 能够帮助实现信号与系统作业习题和相关方程解法(Experiment 3, differential equations discrete signals and systems can help achieve operational exercises and related equations for)
