) As Double

C++/CLI

public:
virtual double Evaluate(
	IReadOnlyList<double>^ point
)

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

public abstract double Evaluate(
	ReadOnlySpan<double> point
)

Visual Basic

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

C++/CLI

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

abstract 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 surface at the specified point.

Remarks

The length of point must equal Dimension.

Exceptions

ArgumentException

Evaluate(IReadOnlyList<Vector<Double>>, Span<Double>)

Evaluates the surface at multiple points specified by a list of vectors.

public virtual void Evaluate(
	IReadOnlyList<Vector<double>> points,
	Span<double> destination
)

Visual Basic

Public Overridable Sub Evaluate ( 
	points As IReadOnlyList(Of Vector(Of Double)),
	destination As Span(Of Double)
)

C++/CLI

public:
virtual void Evaluate(
	IReadOnlyList<Vector<double>^>^ points, 
	Span<double> destination
)

abstract Evaluate : 
        points : IReadOnlyList<Vector<float>> * 
        destination : Span<float> -> unit 
override Evaluate : 
        points : IReadOnlyList<Vector<float>> * 
        destination : Span<float> -> unit

Parameters

points IReadOnlyList<Vector<Double>>: A read-only list of vectors, where each vector represents a point in N-dimensional space.
destination Span<Double>: A span to receive the computed values.

Remarks

This method evaluates the surface at each point in points and stores the results in destination.

The default implementation loops through the list and calls Evaluate(ReadOnlySpan<Double>) for each point.

Exceptions

ArgumentNullException

points is null.

ArgumentException

Any vector in points has a length that does not equal Dimension.

-or-

destination is shorter than the number of points.

Evaluate(ReadOnlySpan<Vector<Double>>, Span<Double>)

Evaluates the surface at multiple points specified by a read-only span of vectors.

public virtual void Evaluate(
	ReadOnlySpan<Vector<double>> points,
	Span<double> destination
)

Visual Basic

Public Overridable Sub Evaluate ( 
	points As ReadOnlySpan(Of Vector(Of Double)),
	destination As Span(Of Double)
)

C++/CLI

public:
virtual void Evaluate(
	ReadOnlySpan<Vector<double>^> points, 
	Span<double> destination
)

abstract Evaluate : 
        points : ReadOnlySpan<Vector<float>> * 
        destination : Span<float> -> unit 
override Evaluate : 
        points : ReadOnlySpan<Vector<float>> * 
        destination : Span<float> -> unit

Parameters

points ReadOnlySpan<Vector<Double>>: A read-only span of vectors, where each vector represents a point in N-dimensional space.
destination Span<Double>: A span to receive the computed values.

Remarks

This method evaluates the surface at each point in points and stores the results in destination.

The default implementation loops through the vectors and calls Evaluate(ReadOnlySpan<Double>) for each point.

Exceptions

ArgumentException

Any vector in points has a length that does not equal Dimension.

-or-

destination is shorter than the number of points.

Evaluate(Int32, ReadOnlySpan2D<Double>, Span<Double>)

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

public virtual void Evaluate(
	int pointCount,
	ReadOnlySpan2D<double> points,
	Span<double> destination
)

Visual Basic

Public Overridable Sub Evaluate ( 
	pointCount As Integer,
	points As ReadOnlySpan2D(Of Double),
	destination As Span(Of Double)
)

C++/CLI

public:
virtual void Evaluate(
	int pointCount, 
	ReadOnlySpan2D<double> points, 
	Span<double> destination
)

abstract Evaluate : 
        pointCount : int * 
        points : ReadOnlySpan2D<float> * 
        destination : Span<float> -> unit 
override Evaluate : 
        pointCount : int * 
        points : ReadOnlySpan2D<float> * 
        destination : Span<float> -> unit

Parameters

pointCount Int32: The number of points (columns) in the 2D span.
points ReadOnlySpan2D<Double>: A 2D span containing the points in column-major order, where each column represents one point (with pointCount columns) and each row represents a coordinate dimension (with Dimension rows).
destination Span<Double>: A span to receive the computed values.

Remarks

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

The points are stored in column-major order: point i has coordinates (points[0,i], points[1,i], ..., points[Dimension-1,i]).

The default implementation loops through the columns and calls Evaluate(ReadOnlySpan<Double>) for each point. Derived classes may override this method to provide more efficient batch evaluation.

Exceptions

ArgumentException

The row count of points does not equal Dimension.

-or-

destination is shorter than pointCount.
