PiecewiseLinearCurve Class

Represents a curve that has different expressions on different intervals within its domain.

Definition

Namespace: Numerics.NET.Curves
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.4
C#
public class PiecewiseLinearCurve : PiecewiseCurve
Inheritance
Object  →  Curve  →  PiecewiseCurve  →  PiecewiseLinearCurve

Remarks

Use the PiecewiseLinearCurve class to represent a curve or function that looks like a broken line. It is most commonly used for linear interpolation of tabulated data that represents a continuous function. On each interval between two data points, the curve is approximated by a straight line between the data points.

Piecewise linear curves inherit from PiecewiseCurve.

Constructors

Obsolete.
PiecewiseLinearCurve(ReadOnlySpan<Double>, ReadOnlySpan<Double>) Constructs a new PiecewiseLinearCurve object.
PiecewiseLinearCurve(Vector<Double>, Vector<Double>) Constructs a new PiecewiseLinearCurve object.
