利用matlab对方程求根进行了编码计算(Solving the equation using matlab code were calculated)

long line model for 3phase system

this is the implementation of introduced algorithm(feature selection algorithm for mixed data with both nominal and continuous features,Wenyin Tang & K.Z. Mao)

this code filter the band using matlab program

用matlab的simulink环境下搭建的光伏发电仿真模型，内含三个simulink文件，解压后直接运行(PV simulation model used to build the next matlab simulink environment, containing three simulink file, run directly after decompression)

STM32制作的MP3的全部资料，用谱方法计算流体力学一些流动现象的整体稳定性,是路径规划的实用方法。( STM32 all the information produced by the MP3, Spectral methods of computational fluid dynamics flow of some of the overall stability of the phenomenon, Is a practical method of path planning.)

1. 多址接入协议，即Multiple Access。 2. 源码提供了竞争随机接入协议，包括ALOHA（pure和slotted）和基础的CSMA仿真。 3. 定义了业务量、吞吐量、平均传输时延作为系统的性能指标 4. 仿真得到无捕获效应理论曲线、仿真曲线，有捕获效应的仿真曲线。

实现两幅图像的配准，首先对图像做高斯低通滤波处理 ，然后计算互信息值，利用PWELL算法求出最优的参数，根据所得参数进行配准(To achieve the registration of two images, the first image to do the Gaussian low-pass filter, then calculate the mutual information value, use PWELL algorithm to determine the optimal parameters, in the light of registration parameters)

16QAM +AWGN added+BER(16QAM+AWGN added+BER)

针对噪声，用AR2建模，用卡尔曼滤波，并用Allan方差检验(against noise, using AR2 modeling, Kalman filtering, and with Allan variance test)
