站长！这是使用LDA和PCA模式识别方法对人脸特征进行提取计算的Matlab程序框架，比较好！(head! This is the LDA and the use of pattern recognition methods on PCA Facial Feature Extraction for the Matlab program, good!)

把已知的时域信号进行傅里叶变换在频域上显示。(If you are running a lot of time based simulations, often you will want to see the frequency response. Here is a function that may help.)

synchronously rotating model of induction motor

g.722 code for speech compression

matlab 仿真BPSK 内点法 可以运行(matlab simulation of BPSK interior point method)

optical fiber simulation

分型计算李雅普诺夫指数的一个程序，可以参考(Typing a program Lyapunov exponent calculation, reference)

对语音信号进行分析时需要先进行预加重处理，起到提升高频的作用。(The speech signal analysis needs to first conduct a pre-emphasis process, to enhance the role of high frequency. )
