Evaluate(ReadOnlySpan<Double>)

Evaluates the polynomial at the specified point.

public override double Evaluate(
	ReadOnlySpan<double> point
)

Visual Basic

Public Overrides Function Evaluate ( 
	point As ReadOnlySpan(Of Double)
) As Double

C++/CLI

public:
virtual double Evaluate(
	ReadOnlySpan<double> point
) override

abstract Evaluate : 
        point : ReadOnlySpan<float> -> float 
override Evaluate : 
        point : ReadOnlySpan<float> -> float

Parameters

point ReadOnlySpan<Double>: A read-only span representing the coordinates of the point.

Return Value

Double
The value of the polynomial at the specified point.

Remarks

This method computes p(x) = Σᵢ cᵢ · φᵢ(x) where φᵢ are the basis monomials and cᵢ are the coefficients.

Exceptions

ArgumentException

The length of point does not equal Dimension.

Evaluate(Vector<Double>)

Evaluates the polynomial at the specified point.

public double Evaluate(
	Vector<double> point
)

Visual Basic

Public Function Evaluate ( 
	point As Vector(Of Double)
) As Double

C++/CLI

public:
double Evaluate(
	Vector<double>^ point
)

member Evaluate : 
        point : Vector<float> -> float

Parameters

point Vector<Double>: A vector representing the coordinates of the point.

Return Value

Double
The value of the polynomial at the specified point.

Exceptions

ArgumentNullException	point is null.
ArgumentException	The length of point does not equal Dimension.

Evaluate(Matrix<Double>, Vector<Double>)

Evaluates the polynomial at multiple points.

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

Visual Basic

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

C++/CLI

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

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

Parameters

points Matrix<Double>: A matrix where each row represents one point.
result Vector<Double> (Optional): An optional vector to receive the computed values. If null, a new vector is allocated.

Return Value

Vector<Double>
A vector containing the polynomial values at each point.

Exceptions

ArgumentNullException	points is null.
ArgumentException	The number of columns in points does not equal Dimension, or result is not null and its length is incorrect.

Evaluate(ReadOnlySpan2D<Double>, Span<Double>)

Evaluates the polynomial at multiple points stored in column-major layout.

public void Evaluate(
	ReadOnlySpan2D<double> points,
	Span<double> values
)

Visual Basic

Public Sub Evaluate ( 
	points As ReadOnlySpan2D(Of Double),
	values As Span(Of Double)
)

C++/CLI

public:
void Evaluate(
	ReadOnlySpan2D<double> points, 
	Span<double> values
)

member Evaluate : 
        points : ReadOnlySpan2D<float> * 
        values : Span<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.
values Span<Double>: A span to receive the computed polynomial values.

Remarks

This method evaluates the polynomial at each point stored as a column in points and stores the results in values.

Exceptions

ArgumentException

The dimensions of points or values are incorrect.
