does anybody know about en easy way of fitting splines (maybe by using the TSpline classes)?
I face the problem to fit a profile with a combination of 2 range-wise defined functions for which I need a smooth transition. The boundaries of this transition region should be parameters of the fit itself. My idea was to use a 3rd order spline to accomplish this.
So far I’ve used spline interpolation only which gives already a fairly good result. However there are still some small bendings at the intersection points which I want to smooth out by allowing the fit to vary the knot positions.
Thanks in advance,
