Find roots of functions of one variable

This crate provides algorithms over a generic type T to find roots of functions T → T. It is readily usable for T being f64 and f32. Activating the feature rug, one can also use it with rug::Float and rug::Rational.

Usage

use root1d::toms748;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let root = toms748(|x| x*x - 2., 0., 2.).rtol(1e-10).root()?;
    println!("root: {}", root);
}

Highlights

• Efficient & fully generic code.
• Convenient interface with optional arguments and default termination criteria.
• Support for non-copy types (for multi-precision numbers) minimizing the creation of temporary values.
• State of the art root finding algorithm (Toms748) requiring only few evaluations of the function.
