Evaluates the derivatives of the member functions of this FunctionBasis at a specified value.

Namespace: Extreme.Mathematics.Curves
Assembly: Extreme.Numerics (Extreme.Numerics)

Syntax

Visual Basic (Declaration)
Public Function DerivativesAt ( _
	x As Double _
) As GeneralVector
C#
public GeneralVector DerivativesAt (
	double x
)
C++
public:
GeneralVector^ DerivativesAt (
	double x
)

Parameters

x (System.Double)
A real number.

Return Value

A Vector containing the derivatives of the member functions.

Remarks

This method creates a new Vector every time it is called. In some situations, it may be more efficient to call the FillDerivatives(Double, GeneralVector) method instead.

Exceptions

ExceptionCondition
InvalidOperationExceptionNo derivatives are available for this FunctionBasis.
