Struct rand_distr::Triangular

pub struct Triangular<F> where
    F: Float,
    Standard: Distribution<F>,  { /* private fields */ }

The triangular distribution.

A continuous probability distribution parameterised by a range, and a mode (most likely value) within that range.

The probability density function is triangular. For a similar distribution with a smooth PDF, see the Pert distribution.

Example

use rand_distr::{Triangular, Distribution};

let d = Triangular::new(0., 5., 2.5).unwrap();
let v = d.sample(&mut rand::thread_rng());
println!("{} is from a triangular distribution", v);

Implementations

    F: Float,
    Standard: Distribution<F>, 

pub fn new(min: F, max: F, mode: F) -> Result<Triangular<F>, TriangularError>

Set up the Triangular distribution with defined min, max and mode.
