I have to use a natural cubic spline to create a function that interpolates set of data point.
Is possible to do this by using Interpolation or InterpolatingFunction methods?
Looking at the interpolation method, I saw that there is an option InterpolationOrder but paying a bit with it, I was not able to reach a good result.
Thank you in advance,
It might be easier to address this if you post a particular example and the code you tried thus far.
I just found in wolfram library archive a nb which could answers my needs
even if it creates a module which computes the coefficient of the spline function, while I was trying to find a native function in Mathematica which does the interpolation.Anyway, I am looking at the nb and I will be back to you in case of specific question
