Howdy, I have a number of data points that I have fit a spline to using the "SpineFit" add on packages in Mathematica 3.0. What I'm really interested in is the rate of change of the fitted data points. When I list the Input form of the SplineFit function I get a list that seems to contain: 1. The type of spline 2. The range of the spline 3. The data points used to generate the spline. 4. A list of 2x4 lists which are associated with the original data points. My question: Which of the 2 4-member list for each data point contain the coefficients of the interpolating spline? I have tried to recreate the function value at the data points in question using one or the other of the two lists without success. Any help would be appreciated.
