用于ocr图片字母提取的matlab代码，完全自己研究的(Ocr picture letters for extraction matlab code, complete theirself studies)

rgb to cieluv transformation

适用于数学建模，基于matlab的灰色预测代码(For mathematical modeling, based on gray prediction matlab code)

MATLAB 关于交流电机及其故障仿真程序，清华大学博士生做的同步发电机故障诊断实验(MATLAB simulation program about ac motor and its failure, tsinghua university doctoral student of the synchronous generator fault diagnosis experiment)

用Matlab 读写Excel操作，有详细例子(There are detailed examples of Matlab to read and write Excel operation)

说明：  stk和matlab互联的应用，创建简单的gui，可以对场景进行放大缩小(STK and MATLAB interconnected application, create a simple GUI, can zoom in and out of the scene)

采用自相关函数法求基音周期，将采样得到的声音信号按每20ms一帧分为若干帧，并对每帧的序列求自相关函数，取自相关函数第一个最大值点算出基音周期，并以帧为横坐标，基音周期为纵坐标画图，并去除野点，最后取图中浊音部分即面积较大部分的值作为基音周期。(Using the autocorrelation function method pitch period, the sound signal is sampled every 20ms frame is divided into a plurality of frames, and each frame sequence uates the autocorrelation function, taken the first maximum point of correlation function calculated the pitch period, and frame as the horizontal, the vertical axis pitch drawing and remove outliers, and finally take the value of the area that is part of a larger portion of the figure as voiced pitch.)

文件夹“AWGN”说明了系统误码率在均衡前后随SNR增加的变化。 （1）绘制误码率曲线。运行m文件：main_picture,调用主函数：ofdm_AWGN。 （2）绘制星座点图。运行m文件：snr_xinzuotu(Folder )

MATLAB图象处理命令，书中提取出來的图像处理CODE，不用在书里直接找！全都帮你提取出來(MATLAB image processing orders, the book extracted image processing CODE, not in the book directly! All help you extracted)
