TMVA::LogInterval Class Reference

The TMVA::Interval Class.

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

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

    1,10,100,1000

    1,2,4,8,16,32,64,128,512,1024

    or alike ..

Example:
LogInterval(1,10000,5)
i=0 --> 1               note: StepSize(ibin=0) =  not defined !!
i=1 --> 10                    StepSize(ibin=1) = 9
i=2 --> 100                   StepSize(ibin=2) = 99
i=3 --> 1000                  StepSize(ibin=3) = 999
i=4 --> 10000                 StepSize(ibin=4) = 9999
 
LogInterval(1,1000,11)
i=0 --> 1
i=1 --> 1.99526
i=2 --> 3.98107
i=3 --> 7.94328
i=4 --> 15.8489
i=5 --> 31.6228
i=6 --> 63.0957
i=7 --> 125.893
i=8 --> 251.189
i=9 --> 501.187
i=10 --> 1000
 
LogInterval(1,1024,11)
i=0 --> 1
i=1 --> 2
i=2 --> 4
i=3 --> 8
i=4 --> 16
i=5 --> 32
i=6 --> 64
i=7 --> 128
i=8 --> 256
i=9 --> 512
i=10 --> 1024
