图像认证中的Image Hashing技术，源码最新下载自美国名校The University of Texas at Austin的Brian L. Evans教授的实验室网站 (Matlab programs for image hashing downloaded from Professor Brian L. Evans in University of Texas at Austin in USA)

求解一维热方程。空间方向采用四阶差分格式，时间方向采用bvm法(Solving one-dimensional heat equation. Spatial orientation difference scheme with fourth order, the time direction by bvm method)

用matlab做的音频编辑器有滤波功能(Using matlab to do audio editor)

MATLAB不提供现成指数拟合函数，一方面由于但可以轻松通过多项式拟合转化而来，但是使用上还是不如有一个函数方便，所以特写这样一样简单实用的函数(MATLAB does not provide ready-exponential fit function, by hand because it can be easily transformed a polynomial fit, but still not as good as there is easy to use a function, it is as simple close-up of such useful functions)

比较经典格拉姆施密特QR正交分解的matlab源程序(Comparison of the classical Gram Schmidt QR orthogonal decomposition matlab source)

This file contains the 3 responses of any system. This is generalized code

说明：  Market Newman写的复杂网络的加权GN算法 算法用Python写的 其基本思想是不断的删除网络中具有相对于所有源节点的最大的边介数(ege betweenness)的边，然后，再重新计算网络中剩余的边的相对于所有源节点的边介数(The basic idea is to delete the network with respect to all of the source nodes of the largest betweenness (EGE betweenness) edges, then re computing network the remaining edge relative to the boundary of the source node number of all)
