Struct ndarray_interp::interp1d::CubicSpline

pub struct CubicSpline;

The CubicSpline 1d interpolation Strategy

Example

From Wikipedia

let y = array![ 0.5, 0.0, 3.0];
let x = array![-1.0, 0.0, 3.0];
let query = Array::linspace(-1.0, 3.0, 10);
let interpolator = Interp1DBuilder::new(y)
    .strategy(CubicSpline)
    .x(x)
    .build().unwrap();

let result = interpolator.interp_array(&query).unwrap();
let expect = array![
    0.5,
