rootfinder

Root-finding methods for both univariate, scalar-valued functions and multivariate, vector-valued functions.

Examples

Finding a root using the bisection method.

use rootfinder::{root_bisection, Interval};

// Define the function f(x) = x² - 1.
let f = |x: f64| x.powi(2) - 1.0;

// We want the root in the interval [0,∞). Therefore, we use an initial interval of
// [a,b] = [0,9999999]. Finding this root using the bisection method,
let result = root_bisection(f, Interval::new(0.0, 9999999.0), None, None);
let root = result.unwrap();

// `root` is `0.9999999999999999`, which is very close to the true root of 1.
