把yuv格式的专为为avi 把avi格式的转化为yuv(yuv to .avi .avi to yuv)

产生一个有带内相位噪声，毛刺噪声，白噪声的LO信号。(creative a LO signal with in band phase noise， spurs and noise floor.)

很好的短时傅里叶变换的MATLAB程序，适用于初学者。(MATLAB code of short time Fourier transform)

采用离散邻域和模糊邻域两种方法对粗糙集数据进行属性约简，还包含求信息熵程序(Discrete neighborhood and fuzzy neighborhood methods are used to reduce attributes of rough set data, and an information entropy program is included.)

说明：  使用matlab编写的粒子群算法，可用于PID参数整定中。(PSO algorithm for PID parameter tuning)

多光谱读取，tif格式遥感图像在matlab中读取。(Remote sensing image of TIF format read in MATLAB)

this program is a code for DEA, BCC model in matlab programming . I hope that can help you.

振动信号和噪声信号相关性，simulink s函数(Vibration and noise signals correlation, simulink s function)

计算模糊熵，可用于生理信号的变异性分析。本算法降低了个体差异，更易于检测生理状态引起的复杂度改变。(Calculating the fuzzy entropy can be used for variability analysis of physiological signals. The algorithm reduces the individual differences easier to detect changes in the physiological state of the complexity caused.)
