Extrapolation

extrapolate(S::Union{Spline, SplineWrapper}, method::AbstractExtrapolationMethod)

Construct a SplineExtrapolation from the given spline S (which can also be the result of an interpolation).

Flat <: AbstractExtrapolationMethod

Represents a flat extrapolation: spline values at domain limits are extended to the left and to the right.

Linear <: AbstractExtrapolationMethod

Represents a linear extrapolation: splines values extend linearly beyond the left and right boundaries.

Smooth <: AbstractExtrapolationMethod

Represents a smooth extrapolation: derivatives up to order $k - 2$ are continuous at the boundaries.

AbstractExtrapolationMethod

Abstract type representing an extrapolation method.

SplineExtrapolation

Represents a spline which can be evaluated outside of its limits according to a given extrapolation method.
