小世界模型 近日需要用到无标度网络与小世界网络，早上用matlab写了这两种网络的matlab程序，放在这，有用者可以拿去用，请自己验证正确性后使用。 (Small-world model)

Implementation of three phase PLL

这个是面部表情自动识别的源代码。它是基于Viola和Jones的面部检测算法和Gabor面部特征点的提取，然后使用训练过的神经网络来识别人脸表情。(This is the automatic recognition of facial expression source code. It is Viola and Jones face detection algorithms and Gabor facial feature point extraction, and then use the trained neural network based on facial expression recognition.)

说明：  基于matlab搭建PMSM基础控制模型，采用双环PI控制策略。(PMSM basic control model was built based on matlab, and double-loop PI control strategy was adopted.)

说明：  二维的仿真，入射波为空间高斯型，入射到一个单狭缝上透射情况。金属介质为Drude模型(Two-dimensional simulation, the spatial Gaussian incident wave, incident to a single slit on the transmission case. Medium for the Drude model of metal)

this is a veryy useful code a smithchart code for communication

《信号与系统——MATLAB综合实验》配套资料及上课讲义，还有书后拍套光盘源码资料(" Signals and Systems- MATLAB comprehensive experimental" support information and class handouts, as well as making the book CD-ROM source data sets)
