PCA是人脸识别中的一个重要领域，这里有源代码，希望对大家有帮助(PCA is an important field of face recognition, where source code, we want to help)

说明：  用matlab实现变压器的故障诊断，信号的采集，分析，级诊断结果的显示(Transformer with a matlab implementation of fault diagnosis, signal acquisition, analysis, display of level diagnosis)

a=10,b=8/3,c=28.选择不同的初值，仿真Lorenz系统的吸引子。(a = 10, b = 8/3, c = 28. choose different initial simulation of the Lorenz system attractor.)

自己编写的偏最小二乘回归模型matlab程序，附带详细的说明。(Matlab partial least squares regression procedures, with detailed instructions.)

This is an efficient implementation of PCA, which use smaller dimension of the data matrix to compute the eigenvectors

matlab绘图命令，描述了各种绘图用工具，对matlab新手有很好的指导作用(matlab drawing commands, described in a variety of drawing tools, good for novice matlab guide)

自己编写的卡尔曼滤波算法，大家可以参考下。(I have written the Kalman filter algorithm, we can refer to.)

Matlab Uvi_wave wavelet toolbox.(UviWave is a freeware Wavelet Matlab toolbox developed at the University of Vigo, Spain. The package web page is http://www.tsc.uvigo.es/~wavelets/uvi_wave.html.Unfortunately, their server is quite difficult to connect to.)
