Struct LinearInterpolator 

pub struct LinearInterpolator;

Linear Interpolator.

This interpolation method does not require any additional memory.

Trait Implementations

impl BuildInterpolator for LinearInterpolator

fn build(xa: &[f64], ya: &[f64]) -> Result<Self, InterpolationError>

Constructs a Linear Interpolator.

Example

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

Errors

• InterpolationError::UnsortedDataset: xa is not monotonically increasing.
• InterpolationError::DatasetMismatch: xa and ya do not have the same length.
• InterpolationError::NotEnoughPoints: length of xa is less that 2.

const MIN_SIZE: usize = 2

The minimum required number of data points.

impl Clone for LinearInterpolator

fn clone(&self) -> LinearInterpolator

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LinearInterpolator

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Interpolation for LinearInterpolator

fn eval_deriv2( &self, xa: &[f64], _: &[f64], x: f64, _: &mut Accelerator, ) -> Result<f64, Domain1dError>

Always returns 0.

fn eval( &self, xa: &[f64], ya: &[f64], x: f64, acc: &mut Accelerator, ) -> Result<f64, Domain1dError>

Returns the interpolated value y for a given point x, using the data arrays xa and ya and the Accelerator acc.

fn eval_deriv( &self, xa: &[f64], ya: &[f64], x: f64, acc: &mut Accelerator, ) -> Result<f64, Domain1dError>

Returns the derivative dy/dx of an interpolated function for a given point x, using the data arrays xa and ya and the Accelerator acc.

fn eval_integ( &self, xa: &[f64], ya: &[f64], a: f64, b: f64, acc: &mut Accelerator, ) -> Result<f64, Domain1dError>

Returns the numerical integral of an interpolated function over the range [a ,b], using the data arrays xa and ya and the Accelerator acc.
