InterpolateCubicSplineWithDerivatives Method

Create a piecewise cubic Hermite spline interpolation based on arbitrary points and their slopes/first derivative.

Namespace: Altaxo.Calc
Assembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3179.0 (4.8.3179.0)
Syntax
C#
Copy
public static IInterpolation CubicSplineWithDerivatives(
	IEnumerable<double> points,
	IEnumerable<double> values,
	IEnumerable<double> firstDerivatives
)

Parameters

points  IEnumerableDouble
The sample points t.
values  IEnumerableDouble
The sample point values x(t).
firstDerivatives  IEnumerableDouble
The slope at the sample points. Optimized for arrays.

Return Value

IInterpolation
An interpolation scheme optimized for the given sample points and values, which can then be used to compute interpolations and extrapolations on arbitrary points.
Remarks
if your data is already sorted in arrays, consider to use MathNet.Numerics.Interpolation.CubicSpline.InterpolateHermiteSorted instead, which is more efficient.
