Struct rgsl::types::interpolation::InterpType

pub struct InterpType { /* private fields */ }

Implementations

impl InterpType

pub fn min_size(&self) -> u32

This function returns the minimum number of points required by the interpolation object interp or interpolation type T. For example, Akima spline interpolation requires a minimum of 5 points.

pub fn linear() -> InterpType

Linear interpolation. This interpolation method does not require any additional memory.

pub fn polynomial() -> InterpType

Polynomial interpolation. This method should only be used for interpolating small numbers of points because polynomial interpolation introduces large oscillations, even for well-behaved datasets. The number of terms in the interpolating polynomial is equal to the number of points.

pub fn cspline() -> InterpType

Cubic spline 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 point and last point.

pub fn cspline_periodic() -> InterpType

Cubic spline with periodic boundary conditions. The resulting curve is piecewise cubic on each interval, with matching first and second derivatives at the supplied data-points. The derivatives at the first and last points are also matched. Note that the last point in the data must have the same y-value as the first point, otherwise the resulting periodic interpolation will have a discontinuity at the boundary.

pub fn akima() -> InterpType

Non-rounded Akima spline with natural boundary conditions. This method uses the non-rounded corner algorithm of Wodicka.

pub fn akima_periodic() -> InterpType

Non-rounded Akima spline with periodic boundary conditions. This method uses the non-rounded corner algorithm of Wodicka.
