主成分分析并用散点图分析前三个主成分M代码，请指教。(Principal component analysis and scatter analysis of the first three principal components M code, please advice.)

pca code for calculation of pca

This is a basic program to execute the basic requirements of the image pyramid applications using matlab

逐步共线性诊断在成分分析方法降维精确性中的应用(Gradually the collinearity diagnosis analysis method application of reduced- dimension accuracy in composition )

HHT变换matlab程序 在matlab下运行即可，可以修改各种参数，采样点数，各种电能质量原始信号均由程序所得，可以信号叠加而来。比如电压跌落，谐波，暂时上升，中断等。 例子给出的是 电压暂降。(HHT transform matlab matlab program can be run in, you can modify various parameters, sampling points, a variety of power quality of the original signal by the program proceeds, may signal superimposed from. Such as voltage drop, harmonics, temporary rise interruption. The example given is voltage sags.)

光伏系统建模，最大功率点跟踪(MPPT)控制，电流输出型并网(Photovoltaic modeling, MPPT control, current output type grid connection)

有源电力滤波器是用于动态抑制谐波、补偿无功的新型电力电子装置，控制并主动输出电流的大小、频率和相位，并且快速响应，抵消负载中相应电流，实现了动态跟踪补偿，而且可以既补谐波又补无功和不平衡。(APF:Active power filter)

国外计算机科学经典教材 MATLAB科学计算(Abroad, the classic computer science textbook MATLAB scientific computing)

这是matlab宝典里面的源代码 相信对于开发着有所帮助(This is a matlab source code inside the book and I believe that the development of a help)
