Returns the value of the derivative of the B-spline at a point.

Parameters

x

A double which specifies the point at which the derivative is to be evaluated.

ideriv

A int specifying the derivative to be computed.

Return Value

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 first derivative is returned, etc.
