平稳随机信号谱估计 使用两种谱估计方法将信号和噪声分离：周期图法谱估计和Levinson-Durbin递推法谱估计。其中每种方法又细分为自编程序和使用matlab自带函数两种。( Random signal model is estimated using two methods of spectrum signal and noise separation: periodogram spectral estimation method and Levinson-Durbin recursive spectrum estimation method. Each method which is divided into self-fine procedures and the use of two matlab own function.)

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. )
