解L1正则化回归问题（lasso）的Lars算法，MATLAB编译

说明：  matlab语音信号的处理，源文件，M文件··········(matlab voice signal processing, source files, M files)

交流BUCKBOOST拓扑的MATLAB仿真 (AC_BUCK_BOOST )

Good application for images compression.with neural networks

已知语音文件求出其LPC系数后，调用a_lsf_conversion.m函数求其对应的LSF(Known find their voice files LPC coefficients, call a_lsf_conversion.m corresponding LSF function evaluation)

程序理论详见内附的pdf：《Hamilton图的充要条件及圈的矩阵算法》 主程序为 [K]=getPk(A,k) A表示图的邻接矩阵，k表示k阶长路和圈 返回K表示该图的所有k阶长路和圈 其他函数介绍： Ppro定义路的乘法 Psum定义路的加法 MatPro定义路矩阵的乘法 isaPorC判断是否为路或圈 P2subP提取路的和式中的所有路 getP1从邻接矩阵得到1阶路矩阵(get a k-path from a graph)

基于SIFT的图像配准程序 SIFT特征匹配算法是目前国内外特征点匹配研究领域的热点与难点,其匹配能力较强,可以处理两幅图像之间发生平移、旋转、仿射变换情况下的匹配问题,甚至在某种程度上对任意角度拍摄的图像也具备较为稳定的特征匹配能力(Hot and difficult of the current research areas of domestic and foreign feature point matching based the SIFT image registration program SIFT feature matching algorithm is its ability to match between the two images, can handle translation, rotation, affine transformation case match problem, even in some degree images taken at any angle with more stable feature matching ability)

说明：  图像置乱中的仿射变换，优点是加密和解密的不需要周期迭代，图像置乱效果好(it is good for image scrambling becaus of low compute complexity)

二维DOA估计,文件不是很长，还是比较好用的，希望能对大家有所帮助(use for two-dimension DOA estimate.)

维也纳大学的系统级仿真平台说明，讲解清晰。(System-level simulation platform Vienna University of explanation to explain clearly.)
