说明：  用于识别图片中有多少个圆。用户只要用windows下的画图随便画若干个圆（不能交叉，但是可以包含）。保存成256色的bmp格式，该程序就能判断出你画的图片上有多少个圆(Used to identify the picture in many circles. Users only need to use the windows painting random drawing under a number of round (can not cross, but it can contain). Save as 256 color bmp format, the program can determine the picture you draw the number of round)

一种聚类分析算法，实现盲源分离前的盲源数估计。(A cluster analysis algorithm, the number of blind source before blind source separation estimates.)

有关小电流接地的一个系统仿真，对于研究这方面内容的朋友很有用。(For small current grounding system simulation, useful for the study of this aspect of the friend.)

说明：  DCT域的嵌入程序，可以获得较高的鲁棒性，且嵌入秘密信息后的不可感知性也很好。(DCT embedded procedures, get higher robustness, and secret information embedded in the perception is also not very good.)

夫琅和费衍射的matlab仿真，对此方面做了比较详尽阐述(Fraunhofer diffraction of matlab simulation, which has done more elaborate)

感知器算法的matlab实现，欢迎大家指点(Perceptron Algorithm Implementation of Matlab, we welcome guidance)

MATLAB Code for MIMO Receiver design

说明：  matpowe4.1 Open source software, no modified version downloaded from the official website, different matpower may not apply with each other program

下垂控制的matlab仿真,有功和无功的调节。(simulink of droop control，adjust of active power and reactive power.)
