TMVA::Interval Class Reference

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)

          [ min                           max ]

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
