regularizedGamma -- upper regularized gamma function

Usage:

regularizedGamma(s, x)
Inputs:
- s, a real number,
- x, a real number,
Outputs:
- a real number,

Description

This is the (upper) regularized gamma function \(Q(s, x) = \frac{\Gamma(s,x)}{\Gamma(s)}\).

i1 : regularizedGamma(3, 7)

o1 = .02963616388052177

o1 : RR (of precision 53)

i2 : Gamma(3, 7) / Gamma 3

o2 = .02963616388052178

o2 : RR (of precision 53)
