Example 3 according to the specified precision of seeking higher-order equation of the numerical solution of initial value problem.)

说明：  matlab 功能工具 matlab 功能工具(matlab functions matlab function tool tool)

该程序展示了一个10节点的电力系统潮流计算过程，采用牛顿拉夫逊法(The program shows a 10-node power flow calculation, using the Newton Raphson method)

The zip-file contains the following files for visualizing distributions: - distributionPlot.m: main function that allows creating violin plots - histogram.m: generate histograms with ideal bin width given the number of data points and the spread (Freedman-Diaconis rule). Note that for integer-valued data, each integer gets its own bin. - plotSpread.m: plot point clouds with no overlap. Works well for small number of data points, i.e. when there are less than ~20 values per bin.

说明：  文件包含了层次分析法、熵权法和TOPSIS方法计算参数时用到的函数(The file contains the functions used in the calculation of parameters by analytic hierarchy process (AHP), entropy weight method and TOPSIS method)

区别于matlab自带的fft程序，为自主设计的myfft程序代码(Different from matlab' s fft own procedures for self-designed program code myfft)

说明：  双坐标曲线的MATLAB程序。需要的来下载。(Dual process MATLAB curve coordinates. Need to download.)

很经典的书籍哦，有1200多页，非常经典的概率图模型书籍，网上价格一般都1000多元哦！(it is very good for you!)
