Struct Cubic 

pub struct Cubic;

Cubic Interpolation type.

Cubic Interpolation with natural boundary conditions. The resulting curve is piecewise cubic on each interval, with matching first and second derivatives at the supplied data-points. The second derivative is chosen to be zero at the first and last point.

Trait Implementations

impl<T> InterpType<T> for Cubic

where T: Num + Lapack,

fn build( &self, xa: &[T], ya: &[T], ) -> Result<CubicInterp<T>, InterpolationError>

Constructs a Cubic Interpolator.

Example

let xa = [0.0, 1.0, 2.0];
let ya = [0.0, 2.0, 4.0];
let interp = Cubic.build(&xa, &ya)?;

const MIN_SIZE: usize = 3usize

The minimum number of points required by the Interpolator.

const NAME: &str = "Cubic"

The name of the Interpolator.

type Interpolator = CubicInterp<T>

The returned Interpolator, containing the calculated coefficients and providing the evaluation methods.

fn name(&self) -> String

Returns the name of the Interpolator.

fn min_size(&self) -> usize

Returns the minimum number of points required by the Interpolator.
