基于39节点电力系统合闸角调控过程中的机组和负荷的灵敏度计算(Based on 39 bus power system to calculate the standing phase angle regulation of the crew and the load sensitivity)

Image Scaling transaltion rotation codes in matlab

This contain discrete fourier transform code and inverse discrete fourier transform coded in matlab and also contain dfs and idfs

说明：  本文件是用matlab来实现的D-S证据理论代码。可以进行DS证据理论的推到验证(This document is achieved by matlab code DS evidence theory. DS evidence theory can be pushed to the validation)

灰度共生矩阵提取特征值，最近邻算法，进行纹理图像分类。creat_apprentissage用来训练样本，cooccurence是灰度共生矩阵提取特征值，knn是进行k最近邻算法，classif是纹理图像分类(coocurence matrix，using K nearest neighbor to classify textures images.)

基于camshift的人脸跟踪程序，matlab(Face tracking based on Camshift，matlab)

说明：  第二种孤岛运行的控制是采用下垂控制（droop控制），Droop控制就是用来模拟频率一次调整。通过控制电力电子逆变器来实现。(The second kind of island operation control is droop control, Droop control is used to simulate a frequency adjustment. It is realized by controlling the power electronic inverters.)

基于matlab下simulink的模糊控制(fuzzy control)

IEEE 802.11a系统OFDM仿真。假设OFDM系统物理层采用802.11a系统物理层参数，其中，1个长训练符号与6个OFDM数据符号构成1帧，信道为单径瑞丽衰落信道，接收端采用理想信道估计和利用训练符号进行信道估计时的误比特性能(IEEE 802.11a system OFDM simulation Assuming that the OFDM system physical layer uses the 802.11a physical layer parameters, among them, 1 long training symbols and 6 OFDM data symbol consisted of 1 frames, the channel into a single path Ruili fading channel, the receiver uses the ideal channel estimation and utilizes the training symbols to estimate channel bit error performance of the)
