基于crazy climber算法的数字调制信号脊特征提取(陈利民）(Crazy climber algorithm based on digital modulation signal feature extraction ridge)

先生成这样的一幅500*500的RGB彩色图像：一个田字格，左上和右下是绿色，右上是红色，坐下是蓝色。并进行如下处理：（a）将该图像转换到HSI空间，用25*25的平均模板模糊H分量图像，再转换回RGB空间；（b）重复（a），只是这次处理的是S分量。最后简单分析结果。（内含实验报告） (Mr. into a 500* 500 RGB color image: a field word lattice, the upper left and lower right is green, the upper right is red the sit is blue. And be handled as follows: (a) the image into the HSI space, fuzzy H 25* 25 average template component image, and then converted back to RGB space (b) Repeat (a), only this time to deal with the S component . Finally, a simple analysis of the results. (Contains experimental report))

此程序用于在nw小世界网络中求特征根，通过输入节点总数，耦合数值和最大运行次数(This program is used to find the characteristic roots in nw small world networks, by the total number of input nodes, coupling values ​ ​ and the maximum number of runs)

Powerful and fast image inpainting algorithm used convolution based method

implementing Qpsk Mapping

说明：  搭建切换系统的模块，很有用的哦,在此基础上很容易搭建时滞系统的仿真模块哦，还可以提出宝贵的意见修改哦(it is very useful for you to simulation a switched system)

This model gives you the transformation of abc components of voltage and current into dqo components which is mostly used in power systems and power electronics

一个可以提取图像轮廓的小程序，简单易懂，效果不是太好(An image contour can be extracted a small program, easy to understand, the effect is not too good)

说明：  OMP算法，基于压缩感知的正交匹配追踪算法，能够很好的重构出原始信号(OMP algorithm based on compressed sensing orthogonal matching pursuit algorithm that can reconstruct the original signal very good)

This matlab program will give you an overview of spectrum sensing in Cognitive Radio.
