本代码是用来检测图像的局部不变特征的，主要参考DAVID G. LOWE的sift的论文。变成工具是matlab。(This code is used to detect the image of local invariant features, the main reference DAVID G. Lowe s sift paper. Become a tool is Matlab.)

采用猫映射图像加密，有二维三维到四维。都是已经在matlab运行通过的(Cat mapping using image encryption, there are two-dimensional to three-dimensional four-dimensional)

是我见过讲的最详细的关于稀疏信号的书，讲解了稀疏分解，以及书后的程序都是很好用的(Ive seen talking about the most detailed book about the sparse signal, explained the sparse decomposition, and program books are well used after)

该工具包是最新版本的copula工具厢。可实现copula建模，并有copula函数可选择。((The toolkit is the latest version of the pair copula toolkit. The copula modeling of high dimensional data can be realized, and sometimes the copula function can be selected.))

svm 分类小例子，准确率较高。有可能是样本较少或者是样本数据取得太好的缘故。(svm classification)

估计Hilbert矩阵的2条件数和矩阵的阶数的关系用Gauss消去，分别用Gauss消去，Jacobi迭代，Gauss-seidel迭代，SOR迭代和共轭梯度法求解，比较结果。(Discuss the 2 condition number of the matrix and the matrix order relations.Using different methods like Gauss，Jacobi，Gauss-seidel，SOR and GS)
