grid_segmentation

design and source code for simulating PLL components with matlab

说明：  PCA人脸识别 This package implements basic Principal Component Analysis in Matlab and tests is with grayscale portion of the FERET database. Images are not preprocessed and it is up to the user to preprocess the images as wanted, not changing the filenames(PCA Face Recognition This package implements basic Principal Component Analysis in Matlab andtests is with grayscale portion of the FERET database.

Artificial Neural Networks

三相逆变器空间矢量脉冲调制变换matlab仿真(Three-phase inverter space vector pulse modulation transform matlab simulation)

单相全桥PWM整流模型，多次验证表明，该模型动态响应快，静态误差小，完全符合要求。(The single-phase full bridge PWM rectifier model, verified the model many times, fast dynamic response, static error is small, fully meet the requirements.)

由于Kmeans聚类分析是一个局部的搜索过程，因此加入遗传算法进行全局搜索选择最优的初始中心点使得Kmeans算法产生较大的改进(Since Kmeans Cluster analysis is a local search process, so join a global search for the genetic algorithm to the optimal initial centers such Kmeans algorithm produces greater improvement)
