Struct std::rand::distributions::Exp

pub struct Exp {
    lambda_inverse: f64,
}

Unstable (rand)

: use rand from crates.io

The exponential distribution Exp(lambda).

This distribution has density function: f(x) = lambda * exp(-lambda * x) for x > 0.

Fields

lambda_inverse

Unstable (rand) : use rand from crates.io lambda stored as 1/lambda, since this is what we scale by.

Methods

impl Exp

fn new(lambda: f64) -> Exp

Unstable (rand)

: use rand from crates.io

Construct a new Exp with the given shape parameter lambda. Panics if lambda <= 0.
