Compute the lower regularized incomplete Gamma function P(a, x)
.
The lower regularized incomplete Gamma function is defined as:
\(P(a, x) = gamma(a, x) / Gamma(a) = 1 - Q(a, x)\)
where
\(gamma(a, x) = \\int_{0}^{x} t^{a-1} exp(-t) dt\)
is the lower incomplete Gamma function.
Note, above Q(a, x)
(Igammac
) is the upper regularized complete
Gamma function.
