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
