一个变压器励磁涌流的仿真案例，考虑磁滞的影响(A transformer inrush current simulation case, consider the impact of hysteresis)

说明：  基于VQ的说话人识别程序 分为训练和识别两个步骤 具体请见程序(VQ-based speaker recognition process is divided into training and to identify the specific two-step procedure, see)

Research of random signals. Fast Furier transform. Histograms and graphs made in Matlab. Lab work in Omsk state technical university.

2008年出版的，最新的第四版的讲信号与系统建模和simulink的书籍，很是适合通信专业的参考！同时也可以作为matlab扫盲的书(Published in 2008, the latest talk about the fourth edition of Signals and Systems Modeling and simulink books, it is a reference for communication professionals! At the same time can also book as a literacy matlab)

粒子群算法 粒子群优化算法(PSO)是一种进化计算技术(evolutionary computation)，有 Eberhart博士和kennedy博士发明。源于对鸟群捕食的行为研究PSO同遗传算法类 似，是一种基于叠代的优化工具。系统初始化为一组随机解，通过叠代搜寻最优 值。但是并没有遗传算法用的交叉(crossover)以及变异(mutation)。而是粒子在 解空间追随最优的粒子进行搜索。(pso 粒子群优化算法(PSO)是一种进化计算技术(evolutionary computation)，有 Eberhart博士和kennedy博士发明。源于对鸟群捕食的行为研究PSO同遗传算法类 似，是一种基于叠代的优化工具。系统初始化为一组随机解，通过叠代搜寻最优 值。但是并没有遗传算法用的交叉(crossover)以及变异(mutation)。而是粒子在 解空间追随最优的粒子进行搜索。)

说明：  PSO的基本程序和3种经典的改进程序，包括GPSO，ARPSO和HPSO，文件包中没有附这三种改进PSO的源论文，请自行下载(PSO)

PCA主成分分析，是一种常用的基于变量协方差矩 阵对信息进行处理、压缩和抽提的有效方 法。 (PCA principal component analysis, is a common and effective method is based on the covariance matrix of variable information processing, compression and extracted.)

数值积分MATLAB代码，包含4种数值积分方法，分别为复化梯形、复化抛物线、梯形逐次分半、抛物线逐次分半。且编写采用向量化思维效率高、代码简洁。(Numerical integration MATLAB code, including four kinds of numerical integration methods are Trapezoidal, Compound Parabola trapezoid successive half parabolic successive half. And prepared to quantify the use of high-efficiency thinking, concise code.)

说明：  MainGA12.m是主文件，其余两个是被调用文件。 MainGA12.m里主要设置有关参数。(Mainga12.m is the main file, and the other two are called files..Mainga12.m mainly sets the relevant parameters.)
