sparsity preserving projections (SPP)方法，根据论文《sparsity preserving projections with applications to face recognition》使用AR人脸数据库(sparsity preserving projections (SPP)method, according to the paper "sparsity preserving projections with applications to face recognition", using the AR face image database)

Several methods for solving equations matlab

薛定宇和陈阳泉所著《高等应用数学问题的MATLAB求解》一书的配书光盘。含有大量实例，简单易懂。(The XueDingYu and ChenYangQuan "higher math problems to solve application MATLAB in the book of books with CDS.)

包含一份程序代码、一幅运行结果图和一篇说明文档。用于电力系统稳态分析的程序，是PQ法潮流计算的典型应用，针对四机十一节点的电力系统，经仿真测试通过，有较强的参考价值。 (It contains a copy of the program code, the results of a run and a diagram documentation. A program for steady-state analysis of the power system, a typical application PQ load flow calculation method for the four planes eleven nodes power system, the simulation test is passed, there is a strong reference value.)

《MATLAB神经网络30个案例分析》中的第20个例子，案例20 神经网络变量筛选—基于BP的神经网络变量筛选。希望对大家有一定的帮助！(The MATLAB neural network analysis of 30 cases of example, 20 cases of 20 neural network variable selection- based on BP neural network of variable selection. Hope to have certain help to everybody!)

模式识别预处理 分类 后处理的程序 matlab 代码(Pattern recognition preprocessing classification post-processing)

说明：  基础noma仿真程序，适合初期学习用，实现两用户(Basic noma simulation program, suitable for initial learning, to achieve two users)

bpsk、qam调制在高斯瑞利赖斯信道下的simulink仿真(In qam modulation BPSK, gaussian Rayleigh rice channel of simulink )

匹配小波的算法仿真。对原始信号进行匹配小波分解后再进行重构，从图中可以看出消噪性能优越。(It s a simulation of match wavelet algorithm. The primitive signal is decomposed by match wavelet and then reconstructed.It is can be seen from the figure that the method has a good denoise performance.)

利用matlab计算有限元计算，得到流场，划分网格为结构网格。(Take use of finite Element method to calculate the flow field, and get the result of the computation. Structure is used in this code.)
