BSpline.Derivative Method (Double[], Int32)

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

public double[] Derivative(
   double[] x,
   int ideriv
);

Parameters

x
A double array of points at which the derivative is to be evaluated.
ideriv
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.
