Struct peroxide::numerical::spline::CubicSpline

pub struct CubicSpline { /* fields omitted */ }

Cubic Spline (Natural)

Methods

impl CubicSpline

pub fn from_nodes(node_x: Vector, node_y: Vector) -> Self

Examples

extern crate peroxide;
use peroxide::*;

let x = c!(0.9, 1.3, 1.9, 2.1);
let y = c!(1.3, 1.5, 1.85, 2.1);

let s = CubicSpline::from_nodes(x, y);

for i in 0 .. 4 {
    println!("{}", s.eval(i as f64 / 2.0));
}

pub fn eval<T>(&self, x: T) -> f64 where
    T: Into<f64> + Copy, 

Evaluate cubic spline with value

Examples

extern crate peroxide;
use peroxide::*;

let x = c!(0.9, 1.3, 1.9, 2.1);
let y = c!(1.3, 1.5, 1.85, 2.1);

let s = CubicSpline::from_nodes(x, y);

s.eval(2.0);
