10個MATLAB處理運算方法,影像強化灰階二值等,看看(10 MATLAB method of processing algorithms, image enhanced gray-scale value of 2 and so on, to see)

braking of induction motor.

自备matlab函数说明工具箱，非常全；我经常用来查询函数(Own toolbox matlab function that is very wide I always used to query function)

三相电路的svpwm,仿真实现，很难找到的给做仿真的兄弟(Three-phase circuits svpwm, simulation, it is difficult to find the brothers to do simulation)

this is used to find motion compensation. this is matlab code

信号为两个正弦信号加高斯白噪声，用levinson递推法进行功率谱估计。(Signal for two sinusoidal signal plus Gaussian white noise, with levinson recursive power spectrum estimation method.)

this codw is a simulation of photonic crystal 1 dimentional array dispersion

可对地震波进行积分和基调运算，适合研究生做课题研究。(For get the real displacement ,we can get it by two times integral. But we need to do baseline adjustment.)
