Namespace: Numerics.NET
Assembly: Numerics.NET.Tensors (in Numerics.NET.Tensors.dll) Version: 10.1.0

Overload List

GridLinearInterpolator(IReadOnlyList<IReadOnlyList<Double>>, Tensor<Double>, GridBoundaryCondition, ExtrapolationMode)

Creates a grid-based linear interpolator over an N-dimensional rectilinear grid.
C# 
public static GridSurface GridLinearInterpolator(
	IReadOnlyList<IReadOnlyList<double>> axes,
	Tensor<double> values,
	GridBoundaryCondition boundaryCondition = default,
	ExtrapolationMode extrapolation = ExtrapolationMode.Throw
)

Parameters

axes  IReadOnlyList<IReadOnlyList<Double>>
The coordinate vectors for each dimension.
values  Tensor<Double>
The grid values in flat, row-major storage.
boundaryCondition  GridBoundaryCondition  (Optional)
 
extrapolation  ExtrapolationMode  (Optional)
The extrapolation mode for out-of-range coordinates.

Return Value

GridSurface
A LinearGridSurface that performs multilinear grid interpolation.

Exceptions

ArgumentNullExceptionaxes or values is null.
ArgumentException The product of axis lengths does not equal the values length, or an axis has fewer than 2 points.

GridLinearInterpolator(IReadOnlyList<Double>, IReadOnlyList<Double>, IReadOnlyList<Double>, Tensor<Double>, ExtrapolationMode)

Creates a grid-based linear interpolator over a 3D rectilinear grid.
C# 
public static GridSurface GridLinearInterpolator(
	IReadOnlyList<double> xAxis,
	IReadOnlyList<double> yAxis,
	IReadOnlyList<double> zAxis,
	Tensor<double> values,
	ExtrapolationMode extrapolation = ExtrapolationMode.Throw
)

Parameters

xAxis  IReadOnlyList<Double>
The x-coordinates of the grid points.
yAxis  IReadOnlyList<Double>
The y-coordinates of the grid points.
zAxis  IReadOnlyList<Double>
The z-coordinates of the grid points.
values  Tensor<Double>
The grid values in flat, row-major storage.
extrapolation  ExtrapolationMode  (Optional)
The extrapolation mode for out-of-range coordinates.

Return Value

GridSurface
A LinearGridSurface that performs 3D trilinear interpolation.

Exceptions

ArgumentNullExceptionxAxis, yAxis, zAxis, or values is null.
ArgumentException The values length does not match the product of axis lengths, or an axis has fewer than 2 points.
