Principle component Analysis based face recognition system

实现了1999年huang等人提出的基本MNF算法，经验证可运行。(Huang et al 1999 MNF algorithm, proven run.)

PCM编码把模拟信号转换为数字编码，在通信电路的目的地，脉冲调制解调器将二进制的数字编码重新转换成那些在调制器中有相同量子水平的脉冲。(PCM encoding to convert analog signals to digital encoding, the destination of the communication circuit, the binary pulse modem re-converted into digital code modulator in which the quantum level of the same pulse.)

It is a quite useful way to learn Matlab in beginning level

用Matlab编写可一个可看的时钟模拟器，指针形式不是数值形式。(Using Matlab to write a simulator to see the clock, not the form of a pointer value in the form.)

多层板的lamb波，一个工具箱，使用起来简单方便(multi-layer lamb wave, a toolbox, easy to use)

说明：  信号经过滤波器，会发生相移，本程序设计了零相位滤波器，矫正相位(The signal passes through the filter, will occur the phase shift, this procedure designs the zero phase filter, corrects the phase)

three phase Bridge Rectifier Circuit with different type of RLE with Simulation in matlab.
