VectorMathToROVectorStructAmendedUnshifted(Double, Int32, Double, Double) Method

Wraps a double[] array till a given length to get a struct with an [!:IReadOnlyList<double>] implementation. The wrapping is done lazily, i.e. you can access elements with indices below zero and above usedlength, which is normally forbidden. The values for that are given as parameters.

Namespace: Altaxo.Calc.LinearAlgebra
Assembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3179.0 (4.8.3179.0)
Syntax
C#
Copy
public static VectorMathRODoubleArrayWrapperStructAmendedUnshifted ToROVectorStructAmendedUnshifted(
	this double[] array,
	int usedlength,
	double amendedValueAtStart,
	double amendedValueAtEnd
)

Parameters

array  Double
The array to wrap.
usedlength  Int32
Length of the resulting vector. Can be equal or less the length of the array. The first element of the array has index 0 in the returned vector.
amendedValueAtStart  Double
Value of the vector at indices less than zero.
amendedValueAtEnd  Double
Value of the vector at indices greater then or equal to usedlength.

Return Value

VectorMathRODoubleArrayWrapperStructAmendedUnshifted
A wrapper struct with the [!:IReadOnlyList<double>] interface that wraps the provided array, and allows access to elements below and above the valid indices of the array.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type Double. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
