Two matlab files to demonstrate how to fit an ellipsoid directly to a set of 3D points.

说明：  sift特征匹配代码，并带有相关说明文档(SIFT feature matching code with relevant documentation)

利用小波变换将信号中的各频率分开，得到低频信号和高频信号(Wavelet transform of the frequency of the signal separated by low-frequency signal and high frequency signals)

说明：  matlab代码功能实现图像的距离变化，已经通过调试成功！(matlab code image of the distance function changes have been adopted successfully debug!)

自己按照TPAMI文章编写的approximate pairwise accuracy criterion (aPAC)。已测试无误，并提供该代码所对应的文章。(This matlab code is writtern by myself,namely approximate pairwise accuracy criterion (aPAC)。The paper corrsponding to code is also provided.)

使用matlab编辑M文件，模拟菲涅尔衍射显现象，压缩包中包含了4个M文件(M file editing using matlab to simulate the phenomenon of Fresnel diffraction significant)

特征惩罚算法 对手竞争学习算法 matlab程序源代码哦(Characteristics of punishment algorithm rival competitive learning algorithm matlab program source code Oh)

说明：  生成复杂网络之BA无尺度网络，有详尽的原理描述和参数说明。(BA generate complex networks of scale-free networks, there is a detailed description of the principles and parameters.)

struct2的一个列子，简单的描述了struct2的配置和测试使用(A Lie struct2 and simple description of the configuration and testing of the use of struct2)
