Returns the value of the derivative of the B-spline at each point of an array.

Namespace: Imsl.Math
Assembly: ImslCS (in ImslCS.dll) Version: 6.5.0.0

Syntax

C#
public double[] Derivative(
	double[] x,
	int ideriv
)
Visual Basic (Declaration)
Public Function Derivative ( _
	x As Double(), _
	ideriv As Integer _
) As Double()
Visual C++
public:
array<double>^ Derivative(
	array<double>^ x, 
	int ideriv
)

Parameters

x
Type: array< System..::.Double >[]()[]
A double array of points at which the derivative is to be evaluated.
ideriv
Type: System..::.Int32
A int specifying the derivative to be computed.

Return Value

A double array containing the value of the derivative the B-spline at each point of the array x.

Remarks

If ideriv is zero, the function value is returned. If one, the first derivative is returned, etc.
