实现两个序列的循环卷积，输出卷积后的序列结果(Implement circular convolution of two sequences, the results of the output sequence after convolution)

bhattacharya cofficient is used to in canny edge detector

这个程序是计算WignerVille用到的，希望对你有用(This program is used in computing WignerVille you)

一些复杂网络的数据集，包括karate，dolphins，football等，分别为n*2和n*n矩阵形式，还有对数据集进行转换的代码(datasets of complex networks)

用teager能量算子来解调出复杂信号的纯调频挑夫函数，用LMD来进行局部均值分解(Pure FM demodulated complex signal porters function with Teager energy operator, using LMD to carry out the local mean)

基于高斯滤波器的图像压缩算法。可以处理真彩图和灰度图，相当实用。(Gaussian filter based on image compression algorithms. Can handle true color pictures and grayscale, quite useful.)

曲线拟合资料，自己学习过程中积累的一些文档，包含多种数据拟合方法。(Curve fitting data, some of the documents accumulated in their own learning process, contains a variety of data fitting methods.)

sift特征点匹配程序，实现特征点匹配，.m文件，直接在matlab中运行即可。(sift feature point matching process, to achieve feature point matching,. m files can be run directly in matlab.)

m文件为程序。最小二乘方法的介绍，从我的论文中截取一段出来，说明原理。N为数据的个数(m file for the program. Least squares method is introduced, from the interception of some of my papers out of that principle. N is the number of data)
