Syntax
- detPlot(data1, data2)
- detPlot(data1, data2, opt)
Description
|detPlot(data1, data2)| plots the DET (Detection Error Tradeoff) curve for classification analysis of a single thresholds.
|detPlot(data1, data2, opt)| plots the DET with given options:
- opt.scaleMode: 'linear' (default) or 'log'
- opt.textRotation: Degrees to rotate the annotation texts ([] for no texts)

Example
data1=randn(1,300)-1; data2=randn(1,300)+1; opt=detPlot('defaultOpt'); opt.scaleMode='linear'; opt.textRotation=20; detPlot(data1, data2, opt);
