Hi,
I'm getting the same while trying to plot incomplete gamma - just the
straight line (ROOT v 5.08/00).
And, I see another problem with the confluent hypergeometric function:
But, when I try to define the function I want to plot, that's the error message:
i.e. in distinct the with incomplete gamma function, I can not even define the confluent hypergeometric function.
Need to use gsl functionality (special functions) included in ROOT.
What am I doing wrong?
Thanks,
George
PS. It would help greatly if syntax gets unified. E.g I can calculate
incomplete gamma using both
root [0] TMath::Gamma(1,2)
and
root [1] ROOT::TMath::Gamma(1,2)
but only
ROOT::Math::conf_hyperg(1,2,3)
works for calculating the value of confluent hypergeometric.
