ROCcurve
ROC曲线~在信号检测理论中,接收者操作特征(receiver operating characteristic),或者叫ROC曲线是一种对于灵敏度进行描述的功能图像.ROC曲线可以通过描述真阳性率(TPR)和假阳性率(FPR)来实现.由于是通过比较两个操作特征(TPR和FPR)作为标准,ROC曲线也叫做相关操作特征曲线(ROC curve ~ in signal detection theory, the receiver operating characteristics (receiver operating characteristic), or called the ROC curve is a function that describes the sensitivity of the image. ROC curve can describe the true positive rate (TPR) and false positive rate ( FPR) to achieve. because it is by comparing the two operating characteristics (TPR and FPR) as a standard, ROC curve is also called the relevant operating characteristic curve)

Matlab Filter Implementation
In this section, we will implement (in matlab) the simplest lowpass filter
$displaystyle y(n) = x(n) + x(n-1), n=1,2,ldots,N $
(from Eq.$ ,$(1.1)). For the simplest lowpass filter, we had two program listings:
Fig.1.3 listed simplp for filtering one block of data, and
Fig.1.4 listed a main program for testing simplp.
In matlab, there is a built-in function called filter3.3 which will implement simplp as a special case. The syntax is
y = filter (B, A, x)
where
x is the input signal (a vector of any length),
y is the output signal (returned equal in length to x),
A is a vector of filter feedback coefficients, and
B is a vector of filter feedforward coefficients.
The filter function performs the following iteration over the elements of x to implement any causal, finite-order, linear, time-invariant digital filter:3.4
