Function rgsl::randist::lognormal::lognormal

pub fn lognormal(r: &mut Rng, zeta: f64, sigma: f64) -> f64

This function returns a random variate from the lognormal distribution. The distribution function is,

p(x) dx = {1 \over x \sqrt{2 \pi \sigma^2} } \exp(-(\ln(x) - \zeta)^2/2 \sigma^2) dx

for x > 0.
