Syntax

public virtual double Derivative(
	double x,
	int ideriv
)

Public Overridable Function Derivative ( 
	x As Double,
	ideriv As Integer
) As Double

public:
virtual double Derivative(
	double x, 
	int ideriv
)

abstract Derivative : 
        x : float * 
        ideriv : int -> float 
override Derivative : 
        x : float * 
        ideriv : int -> float

x: Type: SystemDouble
A double, the point at which the derivative is to be evaluated.
ideriv: Type: SystemInt32
An int specifying the derivative to be computed. If zero, the function value is returned. If one, the first derivative is returned, etc.

Type: Double
A double containing the value of the derivative of the spline at the point x.
