lowpassfilter

文件中包含几个用matlab编写的图像去噪程序，如邻域平均滤波‘维纳滤波法，巴特沃斯滤波法，并给出了计算PSNR值的公式。( delete the noise in the image)

基于 MATLAB 的时域信号采样及频谱分析，是很好的学习时域信号的matlab源代码。(MATLAB-based time-domain signal sampling and spectral analysis, is a very good study of time-domain signal matlab source code.)

analysis of ecg using cepstrum technique.......contains analysis of a normal ecg and 3 abnormal ecg

试者工作特征曲线 （receiver operating characteristic curve，简称ROC曲线），又称为感受性曲线（sensitivity curve）。得此名的原因在于曲线上各点反映着相同的感受性，它们都是对同一信号刺激的反应，只不过是在几种不同的判定标准下所得的结果而已。接受者操作特性曲线就是以虚报概率为横轴，击中概率为纵轴所组成的坐标图，和被试在特定刺激条件下由于采用不同的判断标准得出的不同结果画出的曲线。(PLOTROC Plot receiver operating characteristic. Syntax plotroc(targets,outputs) plotroc(targets1,outputs1, name1 ,targets,outputs2, name2 , ...) Description PLOTROC(TARGETS,OUTPUTS) plots the receiver operating characteristic for each output class. The more each curve hugs the left and top edges of the plot, the better the classification. PLOTROC(TARGETS1,OUTPUTS2, name1 ,...) generates multiple plots. )
