Hi,
Sorry for this unrelated to ROOT question, but I hope someone here could
know the answer.
I need to calculate some Fermi-Dirac integrals (0 to infinity) for
functions in form :
> x^n
> f(x,n,u) = ---------------
> (e^(x - u) + 1)
where n = 2,3,4 (natural) and u = something between 0.0 and 5.0 (real)
Analytical formulas, that I know, use either the Lerch transcendent, or the Jonquiere's (known also as the polylogarithm) function.
I would like to use functions coming from CERNLIB, but none of the above mentioned is implemented. I think there must be another magic function in CERNLIB which can be used to calculate this interval, I just miss the magic formula to do this ...
Thanks in advance,
Best regards,
Jacek.
