Polynomial root-finding in Rust

dependency status Apache 2.0 or MIT license. Build status Crates.io Docs

A small rust crate for numerically finding roots of low-degree polynomials.

use polycool::Poly;

// The polynomial x^3 - 6x^2 + 11x - 6
let p = Poly::new([-6.0, 11.0, -6.0, 1.0]);

dbg!(p.roots_between(-10.0, 10.0, 1e-6));
// [0.9999999999999996, 2.0000000000000018, 2.9999999999999982]

Currently, we implement Yuksel's iterative solver for finding roots within a given interval to a specified target accuracy.
