detPlot
DET (Detection Error Tradeoff) plot for classification analysis of a single feature.
Contents
Syntax
- detPlot(data1, data2)
- detPlot(data1, data2, scaleMode)
Description
|detPlot(data1, data2)| plots the DET (Detection Error Tradeoff) curve for classification analysis of
a single feature. The default axis scale is linear.
If log-scale is desired, use |detPlot(data1, data2, 'log')| instead.

Example
data1=randn(1,300)-1; data2=randn(1,300)+1; opt=detPlot('defaultOpt'); subplot(1,2,1); opt.scaleMode='linear'; detPlot(data1, data2, opt); subplot(1,2,2); opt.scaleMode='log'; opt.textRotation=270; detPlot(data1, data2, opt);
