电网潮流计算中节点导纳矩阵的形成的函数程序，进过验证可以使用(Power flow calculation of the node admittance matrix of the function of the formation process can be used to go to verify)

N个小球的电磁散射，只有偶极子点的相互作用(Scattering by N Small Spheres, dipole point interactions only)

采用zedboard、zynq等在matlab的平台上进行硬件协仿真的，文章介绍Getting Started with HW，环境的搭建和调试方式。(Using zedboard, zynq etc. on matlab platform for hardware co-simulation, the article describes the Getting Started with HW, build and debug mode environment.)

matlab数字水印程序m文件程序，用的是小波变换中的dwt方法，并且把小波变换分成了四个子带，选择的LL子带。svd算法与dwt相结合，加密方法是混沌加密。与我刚才上传的dwt_svd_GUI.rar是一个程序，一个是gui的，一个是m文件。(m digital watermarking matlab program documentation procedures, using a wavelet transform method in the dwt and the wavelet transform is divided into four sub-band, choose the LL sub-band. svd algorithm with a combination of dwt, encryption method is chaotic encryption. I have just uploaded a dwt_svd_GUI.rar procedures, one is the gui, one m file.)

被控对象为G(S)=400/（s*s+500s）,首先运行模糊控制器程序chap4_2.m,并将模糊推理系统保存在a2中，然后运行模糊控制SIMULIK程序。位置指令为0.5sin（10t）,simulink见chap4_3(Controlled object is G (S) = 400/(s* s+500s), first run the fuzzy controller program chap4_2.m, and stored in a2 fuzzy inference system, and then run the fuzzy control SIMULIK program. Position command is 0.5sin (10t), simulink see chap4_3)

採用擬合法求兩曲綫的公切綫，效率很高，精度要求也還能滿足一般需要(Demand curve fitting using the two common tangent, high efficiency, accuracy can also meet the general needs)

This programme is useful to nural network speciallists.

IEC协会推荐的电压波动和闪变的MATLAB计算模型，并含IEC标准（这个标准很难找到免费的）(IEC Association recommended voltage fluctuations and flicker MATLAB computing model, and with the IEC standard (this standard is difficult to find for free))

求函数最大值，可用于一元和二元函数，采用鱼群算法计算(Maximum demand function can be used for unary and binary functions, using fish algorithm)
