Struct sprs_rand::rand_distr::UnitCircle
source · [−]pub struct UnitCircle;
Expand description
Samples uniformly from the edge of the unit circle in two dimensions.
Implemented via a method by von Neumann1.
Example
use rand_distr::{UnitCircle, Distribution};
let v: [f64; 2] = UnitCircle.sample(&mut rand::thread_rng());
println!("{:?} is from the unit circle.", v)
