Struct ExtrapolatingInterpolator 

pub struct ExtrapolatingInterpolator<I: Interpolate1D> { /* private fields */ }

A 1-D interpolant wrapped with configurable out-of-domain behaviour.

The same mode applies to both the lower (x < x_min) and upper (x > x_max) boundaries. Use ExtrapolatingInterpolatorAsymmetric if you need different modes per boundary.

Implementations

impl<I: Interpolate1D> ExtrapolatingInterpolator<I>

pub fn new(inner: I, x_min: f64, x_max: f64, mode: ExtrapolationMode) -> Self

Create a new wrapped interpolant.

Arguments

• inner – The underlying interpolant.
• x_min – Lower bound of the valid domain.
• x_max – Upper bound of the valid domain (must be > x_min).
• mode – Extrapolation strategy.

pub fn eval(&self, x: f64) -> InterpolateResult<f64>

Evaluate the (possibly extrapolated) interpolant at x.

pub fn x_min(&self) -> f64

Domain lower bound.

pub fn x_max(&self) -> f64

Domain upper bound.

pub fn mode(&self) -> &ExtrapolationMode

Reference to the extrapolation mode.
