本文是一片关于FFT的Matlab仿真分析，很具体，配有大量清晰的仿真图片~~有利于FFT初学者的学习(This article is one of the Matlab simulation on the FFT analysis, very specific, clear配有大量simulation picture ~ ~ is conducive to learning for beginners FFT)

原版matlab bpsk信号的调制解调，可显示发送数据的波形，调制后的波形，接收波形，误码情况等(Original matlab bpsk signal modulation and demodulation, send data to display the waveform, the modulated waveform received waveform, error conditions, etc.)

说明：  matlab潮流计算，利用牛顿法计算线路潮流，各位大神进来指点(Matlab power flow calculation, using Newton method to calculate line power flow, you gods come in and give advice)

用scilab（和matlab一样，只是非常小）实现希尔密码的加密与解密(With scilab (and matlab, only very small) the achievement of Hill of encryption and decryption)

说明：  可以解决随机性问题，是一组不错的程序。在均成功运行。大家可以试一试的。(Stochastic problems can be solved, is a good program. Were successfully run in MATLAB.)

对时间序列的批处理和循环利用希望大家批评指正(Use me criticism on the time series of batch processing and recycling)

INTRODUCTION TO MECHATRONICS SYSTEMS

希尔伯特黄变换，提供了EMD分解，希尔伯特包络提取，希尔伯特边际谱绘制(including EMD and envlop extraction using Hilbert and marginal spectrum)

弹性波二维模拟，PLM边界吸收和clayton边界吸收的比较（c++和matlab）(Two-dimensional simulation of elastic waves, PLM boundary absorption and clayton boundary on the absorption of (c++ and matlab))

基于matlab 设计的滤波器程序，很实用。内容包括 FIR数字滤波器的设计、IIR数字滤波器的设计、FFT频谱分析及应用等。(wave filter of matlab )
