PCA是一种掌握事物主要矛盾的统计分析方法，它可以从多元事物中解析出主要影响因素，揭示事物的本质，简化复杂的问题。本程序实现了基于PCA特征脸的人脸识别。(PCA is a major contradiction to grasp things, statistical analysis, it can parse out things from multiple main factors, revealing the essence of things, simplifying complex issues. This program implements the features of face recognition based on PCA.)

谱聚类和SVM相结合的图像分割程序,这是用matlab编的谱聚类程序，该方法能有效的用于数据分类。(This is a matlab procedures for the spectral clustering.The method is effective for data classification.)

西北工业大学博士论文：小型无人机航迹规划及组合导航关键技术研究，是研究组合导航的很好的参考资料(study on the Key Techniques of Trajectory planning and Integrated Navigation of UAV.A Dissertation submitted to Northwestern Polytechnical University in Partial Fulfillment of the Requirement for the Degree of Doctor of Philosophy )

计算单模光纤入射的光纤传感器光强调制函数(Calculated single-mode fiber optical sensor light incident stress system function)

说明：  该程序实现OFDM系统中块状导频的信道估计，块状导频用于时变较慢的多径信道，可以估计出每个载波上的信道传输情况。(The programme realizes channel estimation with block pilots.)

lear N = 10^5 EB_NO = [-1:30] liu1 = zeros(1,N) liu2 = zeros(1,N) for ii = 1:length(EB_NO) m= (2*(rand(1,N)>0.5)-1) + j*(2*(rand(1,N)>0.5)-1) s = (1/sqrt(2))*m normalization of energy to 1 n = 1/sqrt(2)*[randn(1,N) + j*randn(1,N)]

MaYi博士做的多重子空间的算法代码，压缩包里包括文章和matlab代码。对于机器学习的研究者有很大作用(Robust statistical estimation and segmentation of multiple subspaces)

用蚁群算法解决TSP问题，这是我从MATLAB中文论坛找到的。(TSP with ant colony algorithm to solve the problem, which I found from the MATLAB Chinese Forum.)

基于均匀线阵，利用四阶累积量产生虚拟阵元，可估计出比真实阵元数更多的信号源，已达到DOA估计的目的，且具有较好的分辨率。(Based on uniform linear array, using fourth-order cumulants to generate the virtual array element can be estimated more than the true number of array element signal source, the purpose has been to DOA estimation, and has good resolution.)
