Function rgsl::randist::rayleigh::rayleigh

pub fn rayleigh(r: &Rng, sigma: f64) -> f64

[−] Expand description

This function returns a random variate from the Rayleigh distribution with scale parameter sigma. The distribution is,

p(x) dx = {x \over \sigma^2} \exp(- x^2/(2 \sigma²⁾⁾ dx

for x > 0.
