利用3sigma法则判断并剔除粗大误差。使用matlab语言编程。(eliminate wrong data with three-sigma principle)

matlab讲义，附带部分源代码，是一份不错的学习matlab资料，哪个学校的忘记了。(matlab handouts, incidental part of the source code, is a good study matlab data, which schools have forgotten.)

这是数字信号处理的一本专业书，里面有许多的经典的例子，可以作为大家学习数字信号处理的教材。(This is a digital signal processing of a professional book, there are many classic examples, as we learn from digital signal processing of materials.)

说明：  标准极坐标牛顿潮流，包含导纳矩阵生成过程，以中国电力出版社出版《电力系统分析计算机算法》例题2.1为算例(Standard polar coordinates NEWTON, including admittance matrix generation process, with China Electric Power Publishing House &quot power system analysis computer algorithms,&quot Example 2.1 as an example)

说明：  讲解一些Matlab编程基础、Matlab的数据类型、MATLAB语言概述、矩阵和数组、图形基础内容(Learn some basic Matlab programming, Matlab data types, MATLAB language overview, matrix and array, based on the content of graphics)

cohere(x,y,M) computes the coherence function using successive DFTs of length with a Hanning window and 50 overlap. (The window and overlap can be controlled via additional optional arguments.) We see a coherence peak at frequency cycles/sample, as expected, but there are also two rather large coherence samples on either side of the main peak. These are expected as well, since the true cross-spectrum for this case is a critically sampled Hanning window transform. (A window transform is critically sampled whenever the window length equals the DFT length.)

这是本人在学习过程中总结的matlabbode图的绘制技巧，希望对大家有用(This is summarized in the learning process, I the matlabbode map drawing skills, and hope to be useful)
