the-least-square-error-algorithm

说明：  此程序基于matlab环境，实现小波、PCA、像素选大选小融合并有信息熵、平均梯度等融合评价标准(This program is based on matlab environment, and wavelet, PCA, pixel selection and integration of the election have little information entropy, average gradient of integration evaluation criteria)

并用S函数编制相间距离保护和接地距离保护算法程序,构建相应的保护模块,实现了三段式距离保护。仿真结果表明,所建立的三段式距离保护模型能够正确反映在保护区内的不同类型的短路故障并发出动作信号,使断路器跳闸实现输电线路的保护功能。 (A distance protection simulation model of transmission line was established by using Simulink and SimPowerSystem toolbox inMatlab. S-function was used to programe the distance protection of phase faults and earth faults and the relevantprotectionmodelswere created to build distance protection.The simulation results show that the three-stage distance protectionmodel can respond to allkinds of faultswithin protection zones correctly and send correct signal to the breaker of the line. )

pid算法原理解释，对初入学习PID的同学有很大帮助(pid algorithm principle explanation for entering the learning of the students are very helpful PID)

仿真图是速度、距离、幅度三维图像，基于matlab GUI界面设计,用MATLAB实现动态聚类或迭代自组织数据分析，IDW距离反比加权方法，FMCW调频连续波雷达的测距测角，对HARQ系统的吞吐量分析，结合PCA的尺度不变特征变换(SIFT)算法，是路径规划的实用方法。( FIG simulation speed, distance, amplitude three-dimensional image, Based on matlab GUI interface design, Using MATLAB dynamic clustering or iterative self-organizing data analysis, IDW inverse distance weighting method, FMCW frequency modulated continuous wave radar range and angular measurements, HARQ throughput analysis of the system, Combined with PCA scale invariant feature transform (SIFT) algorithm, Is a practical method of path planning.)

K Means Cluster Matlab Source Code

this is a good paper for satellite.

完整的pca小程序，简单的一些数据。进行分类。是模式识别的基础的一些东西(Complete pca applet, simply some of the data. For classification. Pattern recognition is based on something)

说明：  配电网潮流计算（40个节点），采用前推后代的方法(distribution network power flow calculation)

doa,coprime。从2M+N-1根天线扩展到MN-1根天线。M、N均为互质，M小于N(doa, coprime, MUSIC)

是用于模式识别中的一种数据采样方法，此方法是把数据按一定的比例分为训练数据和测试数据。(for pattern recognition of a data sampling methods, This method is data by a certain percentage into training data and test data.)
