Struct FilonIntegral 

pub struct FilonIntegral { /* private fields */ }

Filon integrator for f(x) * {sin,cos}(t x) over an even interval count.

Implementations

impl FilonIntegral

pub fn new(kind: FilonType, t: Real, intervals: Size) -> QlResult<Self>

A Filon integrator against sin/cos of frequency t, splitting the domain into intervals equal sub-intervals.

Errors

Returns an error unless intervals is even and positive, and t is finite and non-zero (Filon’s coefficients divide by t * h).

Trait Implementations

impl Integrator for FilonIntegral

fn integrate_impl<F>(&self, f: &mut F, a: Real, b: Real) -> QlResult<Real>

where F: FnMut(Real) -> Real,

Integrates f over [a, b] for a < b; the Integrator::integrate driver guarantees ordered, non-degenerate limits.

fn integrate<F>(&self, f: F, a: Real, b: Real) -> QlResult<Real>

where F: FnMut(Real) -> Real,

Integrates f over [a, b], handling degenerate (a == b) and reversed (b < a) limits before delegating to integrate_impl.
