) As Double
public:
double Derivative(
double x,
int ideriv
)
member Derivative :
x : float *
ideriv : int -> float
Parameters
- x
- Type: SystemDouble
A double which specifies the point at which the derivative is
to be evaluated.
- ideriv
- Type: SystemInt32
A int specifying the derivative to be computed.
Return Value
Type:
Double
A
double containing the value of the derivative of the
B-spline at the point x.
Remarks
If ideriv is zero, the function value is returned. If one, the
