说明：  kalman滤波，扩展的kalman滤波（EKF），unscented Kalman filter（UKF），基于EKF和UKF混合模型的IMM实现，以及配套的Rauch-Tung-Striebel和two-filter平滑工具，一个很好用的框架(kalman filtering, extended kalman filter (EKF), unscented Kalman filter (UKF), based on the EKF and UKF realize mixed-model IMM as well as ancillary Rauch-Tung-Striebel and two-filter smoothing tool, a very good framework to use)

backstepping applied to tracking problem of a marine vehicle

c均值算法的实现，使用c均值算法对一组三位数据进行聚类，给出了测试的类别数目和初始值。(c-means algorithm, using the c-means algorithm on a set of three data clustering, given the number of categories and initial value of the test.)

将改进的粒子群算法和GA与SVM相结合，通过参数寻优构建新模型完成对空气质量指数的预测(The improved particle swarm optimization and genetic algorithm are combined with SVM. The prediction of air quality index (AQI) is completed by constructing a new model by parameter optimization.)

该程序是使用Matlab仿真协同通信的DF（解码转发）基本性能，基本模型S-R-D三个节点，接收端使用MRC（最大比合并）。固定DF由于SR信道的错误，其性能受到限制，在大SNR情况下不能获得有效分集。而当SR距离足够近的时候，可能获得一定的分集增益(The program is a cooperative communication using Matlab simulation DF (decode forwarding) basic performance, the basic model of the SRD three nodes, the receiver uses the MRC (maximum ratio combining). Fixed DF error of the SR channel, its performance is limited, can not obtain a valid diversity in the large SNR case. When the SR close enough, you may get a certain amount of diversity gain)

一个可运行的潮流计算程序，用牛顿拉弗逊法进行求解。(verry good!)

IEC协会推荐的电压波动和闪变的测量计算方法，并含相关的IEC标准和国标（这些标准很难找到免费的）(IEC Association recommended voltage fluctuation and flicker measurement and calculation methods, and with the relevant IEC standard and GB (hard to find these standards for free))

本程序实现基于Haralick灰度共生矩阵的区域增长在matlab下实现(Implementation of this program based on Haralick GLCM achieved under the regional growth in matlab)
