一个matlab 工具包，可以解决非线性的优化问题，很好用(A matlab toolkit, you can solve the nonlinear optimization problem, and good use)

OMP算法的本质思想是：以贪婪迭代的方法选择D的列，使得在每次迭代的过程中所选择的列与当前冗余向量最大程度的相关，从原始信号向量中减去相关部分并反复迭代，只到迭代次数达到稀疏度K，停止迭代。(OMP compressed sensing )

计算psnr，普通的4:0:0或者灰值图 有范围判断(calculate psnr format 4:0:0 or gray value picture judge for range)

雷达测速与测距（加了白噪声和杂波），包括脉冲压缩、匹配滤波、MTI、MTD、单元恒虚警检测，程序注释特别详细，性能还不错！(Radar and Ranging (plus white noise and clutter), including pulse compression, matched filtering, MTI, MTD, CFAR unit, program comments in particular detail, the performance is not bad!)

MIMO Signals And Systems一书的Matlab程序。(MIMO Signals And Systems of a book on Matlab procedures.)

一个matlab环境下的k近邻分类器,代码中有详细的注释说明,使用方便.(K-Nearest-Neighbor-Classifier MatLab Code)

编辑经典的和修正的格拉姆施密图QR正交化，并用算例比较其区别(Edited and revised the classic Gram Schmidt QR orthogonal graph and compare the difference between a numerical example)
