compute pca for face detection by matlab

说明：  基于Matlab的函数优化遗传算法程序,包含了遗传算法实现的大部分步骤，而且有详细的注释.(Matlab functions genetic algorithm optimization procedures, including the genetic algorithm to achieve the most steps, and detailed notes.)

说明：  PCA-SIFT算法的实现，PCA-SIFT是对SIFT算法的改进，用PCA替代SIFT算法中的第四步，提高了效率，且准确率更高(PCA-SIFT algorithm implementation, PCA-SIFT SIFT algorithm is an improved SIFT algorithm with PCA instead of the fourth step, improve efficiency, and higher accuracy)

用主成分分析法估计出点云中每点的法向量函数(Principal component analysis method for normal estimation in point cloud )

语音信号断点检测MATLAB系统仿真程序详述(Breakpoint detection of speech signals detailed MATLAB simulation program )

本文是一个word文档格式matlab程序，主要讲的是通信系统中最小频移键控的研究（即MSK）文档里面带有仿真的图形和matlab程序，希望对大家有所帮助！(This article is a word document format matlab program, is primarily concerned with the communication system minimum frequency shift keying (MSK) document inside with simulation graphics and matlab program, we want to give you some help!Thank you!)

this m.file produces channel coefficient with some error, in which the estimation error follows a random variable with zero mean and variance of MSE. lat is the latitude of BS places at different cells which is used to determine the number of BSs in the networks

说明：  MATLAB结合autoCAD关于曲面绘图的案例，有参考价值。(MATLAB combines autoCAD drawing on the surface of the case, the reference value.)

这是一个电磁场与电磁波课程的幻灯片。对于初学者非常有帮助。(This is an electromagnetic wave curriculum with the slides. For beginners very helpful.)
