稀疏编码的算法，运行请阅读readme文件，很简单,Sparse coding algorithmsrun matlab and execute: "demo_fast_sc(1)": epsilon-L1 sparsity penalty "demo_fast_sc(2)": L1 sparsity penalty

由正则表达式构造NFA的程序，并可以对输入串模拟正则表达式匹配-This is a C program used in compiling the given regular expression into an equivalent epsilon-NFA, simulated through tracking State sets.

全变分去噪 J=tv(I,iter,dt,ep,lam,I0) 输入: I - 灰度图像, iter - 迭代次数 [1], dt - 时间步长 [0.2], ep - 提升参数epsilon [1], lam - 保真项 lambda [0], I0 - 输入噪声图像 [I0=I] ([]中的是缺省值)- 全变分去噪 J=tv(I,iter,dt,ep,lam,I0) 输入: I - 灰度图像,

黄金分割法代码 功能: 0.618法精确线搜索-function [s,phis,k,G,E]=golds(phi,a,b,delta,epsilon)
