[−][src]Crate nrfind
nrfind
is a crate for finding the roots of arbitrary functions whose derivatives
are known by the Newton-Rahpson method.
Examples
Here, find_sqrt
is used to approximate the square root of 25.1 to within
0.01, with a starting guess of 5, using at most 100 iterations of the NR
method.
use nrfind::find_sqrt; match find_sqrt(25.1, 5.0, 0.01, 100) { Ok(v) => println!("sqrt(25.1) ~= {} within 0.01", v), Err(v) => println!("Could not find sqrt(25.1) within 0.01; closest guess was {}.", v), }
