Struct Linear 

pub struct Linear<S: Scalar> { /* private fields */ }

Piecewise linear interpolant.

Implementations

impl<S: Scalar> Linear<S>

pub fn new(x: &[S], y: &[S]) -> Result<Self, InterpError>

Create a linear interpolant from data points.

Errors

Returns error if fewer than 2 points or data is not sorted.

Trait Implementations

impl<S: Scalar> Interpolant<S> for Linear<S>

fn interpolate(&self, x: S) -> S

Evaluate the interpolant at x. Extrapolates using the first/last segment if x is outside the data range.

fn derivative(&self, x: S) -> Option<S>

First derivative at x, if available.

fn integrate(&self, a: S, b: S) -> Option<S>

Definite integral from a to b, if available.

fn interpolate_vec(&self, xs: &[S]) -> Vec<S>

Evaluate at multiple points.
