Curve.SlopeAt Method

Definition

Namespace: Numerics.NET.Curves
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 10.0.0

Overload List

SlopeAt(Double)	Gets the slope of the curve at the specified X-coordinate.
SlopeAt(Double[])	Gets the slopes of the curve at the specified X-coordinates.
SlopeAt(ReadOnlySpan<Double>)	Gets the slopes of the curve at the specified X-coordinates.
SlopeAt(Vector<Double>)	Gets the slopes of the curve at the specified X-coordinates.
SlopeAt(ReadOnlySpan<Double>, Span<Double>)	Gets the slopes of the curve at the specified X-coordinates.

SlopeAt(Double)

Gets the slope of the curve at the specified X-coordinate.

public virtual double SlopeAt(
	double x
)

Visual Basic

Public Overridable Function SlopeAt ( 
	x As Double
) As Double

C++/CLI

public:
virtual double SlopeAt(
	double x
)

abstract SlopeAt : 
        x : float -> float 
override SlopeAt : 
        x : float -> float

Parameters

x Double: A real number.

Return Value

Double
The slope of the curve at the specified X-coordinate.

Remarks

This method evaluates the derivative of the curve at the point x. By default, the derivative is approximated numerically using central differences.

SlopeAt(Double[])

Gets the slopes of the curve at the specified X-coordinates.

public double[] SlopeAt(
	double[] x
)

Visual Basic

Public Function SlopeAt ( 
	x As Double()
) As Double()

C++/CLI

public:
array<double>^ SlopeAt(
	array<double>^ x
)

member SlopeAt : 
        x : float[] -> float[]

Parameters

x Double[]: An array of X-coordinates.

Return Value

Double[]
An array containing the slopes of the curve at the specified X-coordinates.

SlopeAt(ReadOnlySpan<Double>)

Gets the slopes of the curve at the specified X-coordinates.

public double[] SlopeAt(
	ReadOnlySpan<double> x
)

Visual Basic

Public Function SlopeAt ( 
	x As ReadOnlySpan(Of Double)
) As Double()

C++/CLI

public:
array<double>^ SlopeAt(
	ReadOnlySpan<double> x
)

member SlopeAt : 
        x : ReadOnlySpan<float> -> float[]

Parameters

x ReadOnlySpan<Double>: A read-only span of X-coordinates.

Return Value

Double[]
An array containing the slopes of the curve at the specified X-coordinates.

SlopeAt(Vector<Double>)

Gets the slopes of the curve at the specified X-coordinates.

public Vector<double> SlopeAt(
	Vector<double> x
)

Visual Basic

Public Function SlopeAt ( 
	x As Vector(Of Double)
) As Vector(Of Double)

C++/CLI

public:
Vector<double>^ SlopeAt(
	Vector<double>^ x
)

member SlopeAt : 
        x : Vector<float> -> Vector<float>

Parameters

x Vector<Double>: A vector of X-coordinates.

Return Value

Vector<Double>
A vector containing the slopes of the curve at the specified X-coordinates.

SlopeAt(ReadOnlySpan<Double>, Span<Double>)

Gets the slopes of the curve at the specified X-coordinates.

public virtual void SlopeAt(
	ReadOnlySpan<double> x,
	Span<double> y
)

Visual Basic

Public Overridable Sub SlopeAt ( 
	x As ReadOnlySpan(Of Double),
	y As Span(Of Double)
)

C++/CLI

public:
virtual void SlopeAt(
	ReadOnlySpan<double> x, 
	Span<double> y
)

abstract SlopeAt : 
        x : ReadOnlySpan<float> * 
        y : Span<float> -> unit 
override SlopeAt : 
        x : ReadOnlySpan<float> * 
        y : Span<float> -> unit

Parameters

x ReadOnlySpan<Double>: A read-only span of X-coordinates.
y Span<Double>: A span to receive the slopes of the curve at the specified X-coordinates.

Remarks

This method evaluates the slope at each X-coordinate in x and stores the result in the corresponding position in y.
