Struct argmin::solver::brent::Brent [−][src]
Brent's method
A root-finding algorithm combining the bisection method, the secant method and inverse quadratic interpolation. It has the reliability of bisection but it can be as quick as some of the less-reliable methods.

Implementations
impl<F: ArgminFloat> Brent<F>
[src]
pub fn new(min: F, max: F, tol: F) -> Brent<F>
[src]
Constructor
The values min
and max
must bracketing the root of the function.
The parameter tol
specifies the relative error to be targeted.
