Struct AdaptiveIntegrator 

pub struct AdaptiveIntegrator {
    pub tol: f64,
    pub max_evals: usize,
    pub calls: usize,
}

Adaptive integrator that tracks function evaluation count.

Uses recursive adaptive G7K15 bisection internally.

Fields

tol: f64

Absolute tolerance for the error estimate.

max_evals: usize

Maximum number of function evaluations allowed.

calls: usize

Number of function evaluations used in the last call to integrate.

Implementations

impl AdaptiveIntegrator

pub fn new(tol: f64, max_evals: usize) -> Self

Create a new AdaptiveIntegrator with the given tolerance and evaluation budget.

pub fn integrate( &mut self, f: &dyn Fn(f64) -> f64, a: f64, b: f64, ) -> (f64, f64)

Integrate f on [a, b].

Returns (value, error_estimate). The error estimate is |G15 - G7| accumulated over all subintervals.
