Struct cubic_spline::Spline

pub struct Spline();

Interpolation methods for computation of cubic spline points within the range of a discrete set of known points. Collection for calculate spline points

Methods

impl Spline

pub fn from_flatten_points(points: &[f64], opts: &SplineOpts) -> Vec<f64>

Calculates flat vector of points from known points

Points is vec of [x, y, x, y, ...]

Example

use cubic_spline::{Spline, SplineOpts};

let opts: SplineOpts = Default::default();

let points = vec![10.0, 200.0, 256.0, 390.0, 512.0, 10.0, 778.0, 200.0];

let spline_points = Spline::from_flatten_points(&points, &opts);

assert_eq!(spline_points.len(), 102);

pub fn from_tuples(points: &[(f64, f64)], opts: &SplineOpts) -> Vec<(f64, f64)>

Calculates vector of point tuples from known points

Points is vec of [(x, y), (x, y), ...]

Example

use cubic_spline::{Spline, SplineOpts};

let opts: SplineOpts = Default::default();

let points = vec![(10.0, 200.0), (256.0, 390.0), (512.0, 10.0), (778.0, 200.0)];

let spline_points = Spline::from_tuples(&points, &opts);

let (last_x, last_y) = spline_points.last().unwrap();

assert_eq!(*last_y, 200.0_f64);
