MIMO场景下的迭代SVD分解，用于得到最大的singular value(Iterative SVD in MIMO scenerio)

LTE-A系统上行链路各模块Matlab程序仿真---码块分割程序仿真(LTE-A uplink module of Matlab program simulation--- code block segmentation program simulation)

Power flow calculation is very important to distribution system management, and more and more attention are paid to calculation speed and accuracy due to the booming smart grids which allow interconnection of distributed generation of different kinds.Because of different characteristic features of distribution networks, such as radial structure and high R/X ratio, distribution system load flow analysis differs significantly from transmission systems.

说明：  直流微网继电保护策略实现S-function的M文件，主保护为母线直流差动保护，基于小波分解的高频故障电流保护，后备保护为过电流保护，针对系统为2进2出的微网，只需将电流值输入，其中第一个输入变量为开关，为保护算法控制开始/关闭。(The relay protection strategy of DC microgrid realizes the M file of S-function. The main protection is busbar DC differential protection. The high frequency fault current protection based on wavelet decomposition and the backup protection is overcurrent protection. For the microgrid with 2 in and 2 out of the system, only the current value is input. The first input variable is switch, which starts/closes for the control of the protection algorithm.)

Wiener filter code in matlab

电压空间矢量发生器程序，用于三相全桥电路的脉宽调制技术，属于电力电子与电力传动学科范围。(Voltage space vector generator procedure for three-phase full-bridge pulse-width modulation circuit technology, power electronics and power belong to discipline the scope of transmission.)

根据多行三列的实验数据（x,y,signal)作出contourf图。其中x,y为二位空间位置（或其他概念的二维），signal为在该位置的信号。此代码先将数据按位置不同求平均，再将signal按照其对应的x,y分配到二位矩阵内。最后作图。编这个代码的初衷是为了制作大脑hippocampus区域place cell 活动性的contour 图。(it s a code i made for plotting a contour graph of experimental data (x,y,signal). The data should be n*3 arrays which cannot be plot into contour directly. In fact, it can subplot 6*6 graphs or more, but speed might be slow..... especially, when you want more detailed graphs.)
