segma-delta modulation tech. for sinusoidal using matlab,first run simulink then run the m-file(segma)

此代码很完善，能很好识别人脸。很有用的识别程序(This code is perfect, can well identify the human face. Useful in identification procedures)

Many algorithms for PQRST feature extraction have been reported in the literature, especially algorithms for finding the QRS complex [Pahlm and Sornmo, 1984] [Hamilton and Tompkins, 1986]. In this section, only the feature extraction algorithm used in this work is described.

this package can simulate a rayleigh multipath fading channel .by running the ,exam.m, the channel will be simulated.,siglfade can simulate a simple rayleigh channel . multipath.m use delay and siglefade to simulate a multiath fading channel.

基于神经网络的人脸识别，主要识别人脸的面对的方向，开发环境matlab(Face recognition based on neural networks, mainly face to face identification of the direction, development environment matlab)

可以用来解决磨床的建模问题，对加工工件应该采取何种加工策略给出了合理的解决办法(Grinder can be used to solve the modeling problem, which should be taken to the workpiece processing strategies, a reasonable solution)
