潮流计算的MATLAB源程序 简单潮流计算的牛顿拉夫逊程序，相关的原始数据数据数据输入格式如下： B1是支路参数矩阵，第一列和第二列是节点编号。节点编号由小到大编写 对于含有变压器的支路，第一列为低压侧节点编号，第二列为高压侧节点 编号，将变压器的串联阻抗置于低压侧处理。 第三列为支路的串列阻抗参数。 第四列为支路的对地导纳参数。 第五烈为含变压器支路的变压器的变比 第六列为变压器是否是否含有变压器的参数，其中“1”为含有变压器， “0”为不含有变压器。 B2为节点参数矩阵，其中第一列为节点注入发电功率参数；第二列为节点 负荷功率参数；第三列为节点电压参数；第六列为节点类型参数，其中 “1”为平衡节点，“2”为PQ节点，“3”为PV节点参数。 (MATLAB source of power flow calculation)

无香粒子滤波的一个matlab例程，其中有ekf,ukf,pf,upf(In these demos, we demonstrate the use of the extended Kalman filter (EKF), unscented Kalman filter (UKF), standard particle filter (a.k.a. condensation, survival of the fittest, bootstrap filter, SIR, sequential Monte Carlo, etc.), particle filter with MCMC steps, particle filter with EKF proposal and unscented particle filter (particle filter with UKF proposal) on a simple state estimation problem and on a financial time series forecasting problem. The algorithms are coded in a way that makes it trivial to apply them to other problems. Several generic routines for resampling are provided. The derivation and details are presented in: Rudolph van der Merwe, Arnaud Doucet, Nando de Freitas and Eric Wan. The Unscented Particle Filter. Technical report CUED/F-INFENG/TR 380, Cambridge University Department of Engineering, May 2000. After downloading the file, type "tar-xf upf_demos.tar" to uncompress it. This creates the directory webalgorithm containing the required m files. Go to this di)
