Struct HermiteInterpolator 

pub struct HermiteInterpolator;

Hermite cubic interpolator for a single step.

Uses the values and derivatives at both endpoints to construct a cubic polynomial that matches y and y’ at t and t_next.

Implementations

impl HermiteInterpolator

pub fn interpolate<S: Scalar>(step: &HistoryStep<S>, t: S) -> Vec<S>

Interpolate at time t within a step.

Uses cubic Hermite interpolation: p(θ) = (1-θ)²(1+2θ) y₀ + θ²(3-2θ) y₁ + h θ(1-θ)² f₀ - h θ²(1-θ) f₁

where θ = (t - t₀) / h.

pub fn interpolate_derivative<S: Scalar>(step: &HistoryStep<S>, t: S) -> Vec<S>

Interpolate derivative at time t within a step.
