用matlab编程产生非线性动力系统的时间序列，并对序列做各种分析(Matlab programming with non-linear dynamical systems have time-series, and do all kinds of sequence analysis)

请大家看着办啊(please size up situation and act accordingly ah?)

用平面波展开法计算的二维光子晶体空气孔结构，TM和TE模式的能带图，matlab程序源代码(With the plane wave expansion method to calculate the two-dimensional photonic crystal structure of air holes, TM and TE modes of the energy band diagram, matlab source code)

Robust Vertical Handoff Algorithm for heterogeneous Wireless Environment

matlab提取图像质心和主轴，使用的是matlab图像处理工具箱函数(extraction matlab image centroid and the spindle, using matlab image processing toolbox functions)

watterson信道matlab仿真,瑞利衰落。。。。(This example shows how to simulate High-Frequency (HF) ionospheric channels, based on the models described in Recommendation ITU-R F.1487. In particular, it shows how to simulate the general Watterson channel model, and other simplified channel models used in the quantitative testing of HF modems. It makes use of the Rayleigh multipath fading channel object and the Gaussian and bi-Gaussian Doppler structures from Communications System Toolbox.)

小波工程主要包括一两部分：一、连续小波分析的应用，二、离散小波分析的应用。下面分两个部分分别说明这两个程序的分析结果： 一、连续小波分析： 所用信号为自己构造的三角波和正弦波叠加的信号：s=(-1).^(floor(n/50)+1).*(mod(n,50)-25)*2-(-1).^(floor(n/17)+1).*(mod(n,17)-8.5)*3+1*cos(n/2)*10。其中第一项(-1).^(floor(n/50)+1).*(mod(n,50)-25)*2为一周期为100的锯齿波，第二项-(-1).^(floor(n/17)+1).*(mod(n,17)-8.5)*3为一周期为34的锯波，第三项为一周期为4*pi正(余)弦波。另外叠加了一幅度为5的噪音信号。 程序包包含程序与说明文档。(Wavelet works mainly consists of two parts: first, the application of continuous wavelet analysis, II, Discrete Wavelet Analysis.)

m序列产生子函数 gold序列产生子函数 自相关函数和互相关函数计算子函数 调用子函数[s,k,pn]=m(c,b0)产生第二条m序列(function [Rm]=Rm(golda,goldb) 自相关函数和互相关函数计算子函数 N=11 n=2^N-1 Rm(1)=sum(golda.*goldb)/n for k=1:n-1 Rm(k+1)=sum(golda.*circshift(goldb,[0,k]))/n end Rm )
