Function gamma_lanczos 

Source 
pub fn gamma_lanczos(z: Complex) -> Complex
Expand description

Compute the Gamma function Γ(z) using the Lanczos approximation.

Valid for Re(z) > 0. For Re(z) ≤ 0 the reflection formula Γ(z)·Γ(1−z) = π/sin(πz) is used automatically.

§Arguments

  • z - complex argument

§Returns

Approximation of Γ(z).
