Incomplete Gamma Function
Description
Evaluate an incomplete gamma function:
γ(a, x) = \int_{0}^{x} t^{a-1} e^{-t}dt,
using SLATEC dgami in https://netlib.org/slatec/.
When (x > 0 and a ≥ 0) or (x ≥ 0 and a > 0),
compute the result, otherwise the value is NaN.
Usage
igamma(a, x)
Arguments
a
A positive numeric vector.
x
A nonnegative numeric vector with same length as a.
length.
Value
A vector of values of an incomplete gamma function.
