说明：  IEEE14节点潮流算法，牛顿法，考虑了节点顺序优化(IEEE14 node flow algorithm, Newton method, consider a node sequence optimization)

Scalp EA, very classic and practical, like friends can be learn about

How To Make Pretty Figures With Matlab

一个关于秩和比的源代码，很有用的。快来试试吧！！(One on RSR source code, very useful)

线性化法仿真三个参考节点定位一个定位节点，随机噪声均方差随机分布在[4,10]，多径效应，权重分布在[0.85，1]。(Linearization method simulation of three reference nodes positioning a positioning node, the variance of random noise are randomly distributed in [4,10], multi-path effects, the weight distribution in [0.85,1].)

ITD法模态识别，基于自由振动曲线进行的模态识别(modal analysis)

说明：  本程序是数制转换问题，为十进制数字和罗马数值间的相互转化，本程序用的是函数调用法(This program is the number of system conversion problems, in order to decimal numbers and value of the inter-conversion of Rome, this program using a function call method)

说明：  这是一个基于空时分组编码的MIMO_OFDM通信系统的仿真设计。此系统包括QPSK调制解调，IFFT调制，空时编解码，基于训练符号的信道估计等通信模块。 (This is a space-time block coding based on the MIMO_OFDM Communication System Simulation and Design. This system consists of QPSK modulation and demodulation, IFFT modulation, space time coding and decoding, based on training symbols such as communication channel estimation module.)

this is about 2 x 2 mimo ofdm

说明：  MATLAB编写的经典粒子群程序，实现最基本的函数优化功能。(MATLAB program written in the classical PSO, to achieve the most basic function optimization.)
