Struct Steffen 

pub struct Steffen;

Steffen Interpolation type.

Steffen’s method guarantees the monotonicity of the interpolating function between the given data points. Therefore, minima and maxima can only occur exactly at the data points, and there can never be spurious oscillations between data points. The interpolated function is piecewise cubic in each interval. The resulting curve and its first derivative are guaranteed to be continuous, but the second derivative may be discontinuous.

Trait Implementations

impl<T> InterpType<T> for Steffen

where T: Num,

fn build( &self, xa: &[T], ya: &[T], ) -> Result<SteffenInterp<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 = Steffen.build(&xa, &ya)?;

const MIN_SIZE: usize = 3usize

The minimum number of points required by the Interpolator.

const NAME: &str = "Steffen"

The name of the Interpolator.

type Interpolator = SteffenInterp<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.
