斯皮尔曼秩相关系数，可用于两对序列的相关统计分析，越大表示相关性越强。(Spearman s rank correalation coefficient)

应用于水利上河流的流管划分，输入断面数据和划分流管数量进行流管划分。(Applied to the flow tube is divided on river water conservancy input section data and divided the number of stream flow tube pipe division.)

这是分别基于两电平SVPWM和三电平SVPWM的PMSM矢量控制模型，对初学者比较实用，采用matlab2012以上版本打开！(This is based on two level SVPWM and three level SVPWM PMSM vector control model, more practical for beginners! Use matlab2012 or more to open.)

用来计算PMV-PPD指标 采用了ASHRE的标准算法(Used to calculate the PMV-PPD index of the standard algorithm used ASHRE)

说明：  计算散度涡度等气象要素，还有计算很多诊断量的程序(canculate divergence and vorticity)

改进的快速粒子群优化算法计算含DG配电网无功优化和运行费用最优解(Improved Fast Particle Swarm Optimization for Reactive Power Optimization and Operation Cost Optimization of Distribution Network with DG)

地球物理专业的数值模拟,大家可以参考,也可以在此基础上拓展.(geophysical professional numerical simulation, we can refer to, they can build on this foundation.)

已经设计好的服装销售管理的数据库如有不好之处请多多包涵~！(Has designed clothing sales management of the database if any bad please forgive me ~!)

牛顿－拉夫逊法潮流计算 基本步骤： 　　（1）形成节点导纳矩阵 　　（2）将各节点电压设初值U， 　　（3）将节点初值代入相关求式，求出修正方程式的常数项向量 　　（4）将节点电压初值代入求式，求出雅可比矩阵元素 　　（5）求解修正方程，求修正向量 　　（6）求取节点电压的新值 　　（7）检查是否收敛，如不收敛，则以各节点电压的新值作为初值自第3步重新开始进行狭义次迭代，否则转入下一步 　　（8）计算支路功率分布，PV节点无功功率和平衡节点柱入功率。(Newton-Raphson method flow calculation basic steps : (1) formation of nodal admittance matrix (2) to set up the initial node voltage U, (3) the initial node-generation-related demand. calculated that the constant term formula Vector (4) nodes will be incorporated into the initial voltage-seeking, calculated Jacobian matrix elements (5) solving that equation, seek to amend the vector (6) to strike a new node voltage value (7) to check whether convergence, if not restrained. concentrated in the nodes of the new voltage as the initial value since the first three steps to re-start the narrow iterations. Otherwise, turn into the next (8) Calculation branch power distribution, PV nodes reactive power and balance-node into power.)

等高线拟合源代码（matlab源码），老外编的，水平确实可以，佩服。里面注释挺详细了。(contour fitting source code (Matlab source), a foreigner series, level really can admire. Inside Notes quite detailed.)
