MultivariatePolynomialBasis.EvaluateBasis Method

public Matrix<double> EvaluateBasis(
	Matrix<double> points,
	Matrix<double>? result = null
)

Public Function EvaluateBasis ( 
	points As Matrix(Of Double),
	Optional result As Matrix(Of Double) = Nothing
) As Matrix(Of Double)

public:
Matrix<double>^ EvaluateBasis(
	Matrix<double>^ points, 
	Matrix<double>^ result = nullptr
)

member EvaluateBasis : 
        points : Matrix<float> * 
        ?result : Matrix<float> 
(* Defaults:
        let _result = defaultArg result null
*)
-> Matrix<float> 

Parameters

points  Matrix<Double>

A matrix where each row represents one point. Must have Dimension columns.

result  Matrix<Double>  (Optional)

An optional matrix to receive the computed basis values. If null, a new matrix is allocated. Each row corresponds to one point, and each column corresponds to one basis function.

Return Value

public void EvaluateBasis(
	ReadOnlySpan<double> point,
	Span<double> basisValues
)

Public Sub EvaluateBasis ( 
	point As ReadOnlySpan(Of Double),
	basisValues As Span(Of Double)
)

public:
void EvaluateBasis(
	ReadOnlySpan<double> point, 
	Span<double> basisValues
)

member EvaluateBasis : 
        point : ReadOnlySpan<float> * 
        basisValues : Span<float> -> unit 

Parameters

point  ReadOnlySpan<Double>

A read-only span containing the coordinates of the point. Length must equal Dimension.

basisValues  Span<Double>

A span to receive the computed basis function values. Length must equal BasisCount.

For each basis monomial x^α, this method computes x^α = x₁^α₁ · x₂^α₂ · ... · xₐ^αₐ.

The results are stored in basisValues in the canonical basis order.

public void EvaluateBasis(
	ReadOnlySpan2D<double> points,
	Span2D<double> basisValues
)

Public Sub EvaluateBasis ( 
	points As ReadOnlySpan2D(Of Double),
	basisValues As Span2D(Of Double)
)

public:
void EvaluateBasis(
	ReadOnlySpan2D<double> points, 
	Span2D<double> basisValues
)

member EvaluateBasis : 
        points : ReadOnlySpan2D<float> * 
        basisValues : Span2D<float> -> unit 

Parameters

points  ReadOnlySpan2D<Double>

A 2D read-only span containing the points in column-major order, where each column represents one point and rows represent coordinate dimensions. Must have Dimension rows.

basisValues  Span2D<Double>

A 2D span to receive the computed basis values. Each column corresponds to one point, and each row corresponds to one basis function. Must have BasisCount rows and the same number of columns as points.

This method evaluates the basis at each point stored as a column in points and stores the results in the corresponding column of basisValues.

public Vector<double> EvaluateBasis(
	Vector<double> point,
	Vector<double>? result = null
)

Public Function EvaluateBasis ( 
	point As Vector(Of Double),
	Optional result As Vector(Of Double) = Nothing
) As Vector(Of Double)

public:
Vector<double>^ EvaluateBasis(
	Vector<double>^ point, 
	Vector<double>^ result = nullptr
)

member EvaluateBasis : 
        point : Vector<float> * 
        ?result : Vector<float> 
(* Defaults:
        let _result = defaultArg result null
*)
-> Vector<float> 

Parameters

point  Vector<Double>

A vector containing the coordinates of the point.

result  Vector<Double>  (Optional)

An optional vector to receive the computed basis values. If null, a new vector is allocated.
