TMVA::Interval Class Reference
TMVA

The TMVA::Interval Class.

Interval definition, continuous and discrete

  • Interval(min,max) : a continous interval [min,max]
  • Interval(min,max,n): a "discrete interval" [min,max], i.e the n numbers: min, min+step, min+2*step,...., min+(n-1)*step, min+n*step=max

e.g.:

  • Interval(1,5,5) = 1,2,3,4,5
  • Interval(.5,1.,6) = .5, .6., .7, .8, .9, 1.0

Note: bin counting starts from ZERO unlike in ROOT histograms

  • Interval definition, continuous and discrete
    • Interval(min,max) : a continous interval [min,max]

    • Interval(min,max,n): a "discrete interval" [min,max], i.e the n numbers:

      min, min+step, min+2*step,...., min+(n-1)*step=max

      e.g.:

      • Interval(1,5,5)=1,2,3,4,5
      • Interval(.5,1.,6)= .5, .6., .7, .8, .9, 1.0
Example: Interval(.5,1.,6)

Constructor & Destructor Documentation

◆ Interval() [1/2]

TMVA::Interval::Interval ( Double_t  min,
Double_t  max,
Int_t  nbins = 0 
)

defines minimum and maximum of an interval

  • when nbins > 0, interval describes a discrete distribution (equally distributed in the interval)
  • when nbins == 0, interval describes a continous interval
