this reports explain the effect of ICI in ofdm with matlab code.

PCA Principle component analysis code

sift的matlab代码，用于提取图像的纹理特征(sift matlab code)

该程序可用于求解一维激波管的解析解。压缩包文件包含3个matlab程序，用户可以改变初始条件获得一维激波管某时刻下的物理状态。(this matlab codes is developed for solving shock tube problem with one dimenssion)

EEMD和EMD仿真程序，还有CEEMDAN的程序和范例，亲测可用。(EEMD and EMD simulation program)

说明：  对信道的仿真，采用QPSK调制，分别在瑞利和高斯信道条件下，也包括CRC较验(Simulation of the channel, using QPSK modulation, respectively, Rayleigh and AWGN channel conditions, but also more experience CRC)

closed loop dc motor

The Game: Make the snake grow longer by directing it to the food. Extra bonus points are given from hearts, eat them as fast as possible as amount of bonus points decreases with time. Higher level gives more points for the food but will also make it tougher to steer a long snake as speed increaces. Five different mazes as well as play w/o maze are possible.
