- Help
- I'm using Interpolation[] in MMa to do linear spline
- interpolation, but i need to integrate the function, spline by spline
- so to speak. MMa knows how to differentiate an InterpolatiingFunction,
- but not how to integrate one. So I need to write a simple procedure to do
- this. I planned to take an InterpolatingFunction and make the
- appropriate changes to its representation to generate the integral.
- But I had a look at the structure of the InterpolationFunction for the
- linear case (using InputForm), and managed to work out what the
- coefficients in the InterpolatingFunction do, but I can't figure out
- how it works in the order 2 case. If any one knows how
- InterpolatingFunction[] represents its splines, could you please send
- me a note, or post info to the net?
