Function rgsl::elliptic::legendre::complete::ellint_Pcomp [−] [src]

pub fn ellint_Pcomp(k: f64, n: f64, mode: Mode) -> f64

This routine computes the complete elliptic integral \Pi(k,n) to the accuracy specified by the mode variable mode. Note that Abramowitz & Stegun define this function in terms of the parameters m = k² and \sin^2(\alpha) = k^2, with the change of sign n \to -n.
