Dear all, Is it possible to calculate the first and second derivatives of a cubic spline curve (interpolating through the points) as opposed to a smoothing spline? If so, how is this done? Is it also possible to find the equation of the spline curve that is fitted? Any help is much appreciated. TIA Eric --------------------------------- [[alternative HTML version deleted]]
