rustnomial

This crate provides utilities for operating on polynomials, including: - Parsing polynomials from strings, and creating strings from polynomials - Math operations with polynomials - Integration and derivation of polynomials - Finding polynomial roots

Examples

• Parsing polynomials from / to strings:

```rust use std::str::FromStr;

use rustnomial::{GenericPolynomial, Polynomial};

fn main() { let poly = Polynomial::::from_str("1+x^2-3+11x").unwrap(); // x^2 + 11x - 2 println!("{}", poly); } ```

• Integration ```rust use rustnomial::integral;

fn main() { let poly = integral!(5., 2., 0.); // 1.6666666666666667x^3 + x^2 + C println!("{}", poly); // 2.666666666666667 println!("{}", poly.eval(0., 1.)); } ```

• Derivation ```rust use rustnomial::derivative;

fn main() { let poly = derivative!(5., 2., 0.); // 10x + 2 println!("{}", poly); } ```

• Rootfinding ```rust use rustnomial::{GenericPolynomial, Polynomial};

fn main() { let poly = Polynomial::::new(vec![1., 2.]).pow(9) * Polynomial::new(vec![1., 3.]); // ManyRealRoots([-3.0, -2.0, -2.0, -2.0, -2.0, -2.0, -2.0, -2.0, -2.0, -2.0]) println!("{:?}", poly.roots()); } ```
