电力系统变压器空载合闸时励磁涌流的仿真，设置好了合闸时间，对励磁涌流波形和存在的谐波进行分析，能直观体现励磁涌流的特点。(Power system transformer load switching inrush current simulation, set closing time, the inrush current waveform and the presence of harmonic analysis, can directly reflect the characteristics of the inrush current.)

This is a matlab code for simulating Frost Beamformer

so what should i write, im tired of writting

计算时频图，功率图的程序，运用在matlab里面。可以很好的实现图形(Computing time-frequency map, power map program, use the matlab inside. Can achieve a good graphics)

main函数调用的子函数均可以随意修改,使用方便 模块包括：流程控制模块、卷积编译码模块、交织解交织模块、调制解调模块、OFDM调制解调模块、信道模块(为多径rayleigh信道)、均衡模块 可以正常运行,绝对适合做OFDM研究使用,有详细的注释,我自己写的,很容易理解. 经典收藏!! (The main function calls the subfunctions are free to modify, easy to use modules including: flow control module, convolution encoding and decoding module, interleaving solution intertwined module modem modules, the OFDM modem module, channel module (multipath rayleigh channel ), equalization module can operate normally, absolutely suitable for OFDM study used detailed notes, I wrote it myself, it is easy to understand. classic collection!)

说明：  关于解微分方程的matlab小程序，适合本科生学习使用。(MATLAB in Physics is a four lecture series in MATLAB that is offered to first year physics undergraduate students. This lecture shows how to use MATLAB to simulate physical systems using a range of methods. Projectile motion is analysed using the Symbolic Math Toolbox, then more complicated chaotic systems are simulated using the MATLAB ODE solvers. Some advanced programming techniques such as Object Oriented Programming (OOP) and Graphical User Interface (GUI) programming are briefly covered. The aim of this lecture series is to introduce students to computational methods in MATLAB to solve problems arising in physics that cannot be solved analytically. No prior knowledge of MATLAB is required. Themes of data analysis, visualization, modelling and programming are explored throughout these lectures. )
