[−][src]Function peroxide::numerical::root::bisection
pub fn bisection<F: Fn(AD1) -> AD1>(
f: F,
interval: (f64, f64),
times: usize,
tol: f64
) -> Result<f64, RootError>
Bisection method to find root
Usage
extern crate peroxide; use peroxide::fuga::*; fn main() -> Result<(), RootError> { let x = bisection(f, (0f64, 4f64), 100, 1e-15)?; assert!((x - 3f64).abs() < 1e-15); Ok(()) } fn f<T: AD>(x: T) -> T { x.powi(2) - x * 2f64 - 3f64 }
