说明：  电力系统课程中所概述的潮流计算的MATLAB语言实现版，包含有详细的源代码，程序说明，以及操作说明(Courses of power system load flow calculation as outlined in the MATLAB language edition, contains detailed source code, description of the procedures and operating instructions)

车牌水平矫正中radon变换的应用，注意radon变换检测直线方向有几种，有基于投影最大值的，有基于车牌字符空隙的等。(The level of radon transform plate correction application, pay attention to radon transform to detect straight line there are several, with the maximum value based on the projection, there are gaps in the other characters on license plates.)

MATLAB关于绘图的设置与调整，这里主要举了一个列子说明，包括xy轴的比例、字号、线宽等(related about setting and adjustment of the graphic in matlab)

有关于过滤图像 的MATLAB软件,已经上机运行过,对MATLAB编程非常有用(Filtered image on the MATLAB software has been running on the machine before, is very useful for MATLAB programming)

电力系统及其自动化专业，电力系统分析潮流计算编程，采用N-R法(Systems and automation, power system analysis power flow calculation program，Using the N-R method)

example of using emd

数值计算里经典的欧拉算法的源程序，采用matlab写的，对理解欧拉算法有很大的帮助作用。(Numerical calculation in the classical Euler algorithm source code, using matlab write, for understanding Euler algorithm has a great help.)

对采集到的振动信号进行EMD分解，得到一系列频率不同的经验模态函数IMF分量，可以用来滤波和提取原信号的特征。(The collected vibration signals of EMD, get a series of different frequency components of IMF empirical mode function can be used to filter and extract features of the original signal.)

说明：  利用MATLAB编程实现电力系统中的负荷预测(Realizing load forecasting)
