频谱分析中的倒频谱分析,在故障诊断和声音信号处理方面很常用(The inverted spectrum analysis spectrum analysis in fault diagnosis and sound signal processing is commonly used)

Logistic映射与奇异吸引子 一、logistic映射---通向混沌的道路 混沌系统，由于其行为的复杂性，往往认为其动态特性（运动方程）也一定非常复杂，事实并非如此，一个参量很少、动态特性非常简单的系统有时也能够产生混沌现象，以一维虫口模型为例，假设某一区域内的现有虫口数为yn，(logistic实现6蛛网迭代)

以梯度投影法迭代直接求解出观测值的改正数，给出一个简单算例，以资验证。 (The correction of the observation is obtained by the interation with gradient projection method and a simple calculation example is given to verify it)

复杂网络中有一些常见的基本模型，如随机图，WS小世界网络，NW小世界网络及BA无标度网络等，本程序从这些网络的产生机理，生成了这些复杂网络模型，并且分析了其基本性质如平均路径长度，聚类系数及度分布等。(Complex networks have some common basic model, such as random graph, WS small-world networks, NW small-world networks and scale-free BA network, the program generated from the mechanism of these networks to generate the complex network model and analysis its basic nature, such as the average path length, clustering coefficient and degree distribution.)

这是线形系统理论中的同步混沌问题 虽然很简单 但有利于我们理解混沌的内容及方法(Chaos of MATLAB problems about line system )
