本文提出了一种节点密度和剩余能量传感器网络加权分群算法，该分群算法优化了群首 选择，均衡了网络节点的能量消耗，延长了网络的生命周期(This paper proposes a residual energy of sensor nodes in the network density and weighted clustering algorithm, the clustering algorithm to optimize the group' s first choice, balancing the energy consumption of network nodes to extend the network life cycle)

对于数据的分类和处理有很大帮助的函数用法。(Be of great help for the classification of the data and processing functions usage.)

1.采用C均值聚类算法对男女生样本数据中的身高、体重2个特征进行聚类分析，考察不同的类别初始值以及类别数对聚类结果的影响，并以友好的方式图示化结果。 2.采用分级聚类算法对男女生样本数据进行聚类分析。分别尝试采用身高，体重，喜欢数学，喜欢文学，喜欢运动，喜欢模式识别共6个特征，以及身高，体重2个特征进行聚类，对比聚类结果，并以友好的方式图示化结果 (1. The use of C means clustering algorithm on sample data for boys and girls in the height, weight 2 characterized in cluster analysis to investigate the initial values of the different categories and the effect on the number of classes of the clustering result, and in a friendly way of illustration result. 2. Using hierarchical clustering algorithm to male and female students sample data clustering analysis. Try both using height, weight, like math, like literature, like sports, like pattern recognition feature a total of six, as well as height, weight, two features clustering, comparing clustering results, and in a friendly way of illustration of the results)

自己搭建的直流微电网的模型，PV模型包含MPPT算法，结果都很好！(Built a DC microgrid model, PV model contains MPPT algorithm, the results are very good!)

说明：  在matlab中直接运行程序，将会显示包含谐波的时域、频域图，设计一个滤波器，滤除谐波，得到滤除谐波后的图形。(Run the program directly in matlab will display a harmonic of the time domain, frequency domain, to design a filter, harmonic filter, harmonic filter obtained after the graphics.)

使用matlab对两幅图像进行匹配，效果很好，值得参考！(Using matlab to match two images of the good results, it is also useful!)

混沌粒子群优化（CPSO, Chaos Particle Swarm Optimization）算法融合了PSO算法的快收敛和CO算法的遍历随机等特点，在PSO算法每一代挑选出的最优解附近的区域里，用混沌算法进一步搜索，防止其陷入局部最优值，从而改进了PSO算法的不足，成为一种高效的优化算法。(Chaotic Particle Swarm Optimization (CPSO, Chaos Particle Swarm Optimization) algorithm combines the features of the PSO algorithm fast convergence and CO traversal algorithm randomly each generation in the PSO algorithm selected area near the optimal solution, further chaos algorithm search prevent it from falling into local optimal value, thus improving the deficiencies of the PSO algorithm, an efficient optimization algorithm.)
