Hey Nikola,

sorry for replying to such an old post. I came accross your smoothing spline implementation in this forum and it works really nice. However as soon as I use three input parameters, i.e. weighted data, the final result has discontinuities at the breakpoints (between the segments of data points). Obviously there is a bug somewhere. Could you tell me what are the requirements on the vector of weights? I have tried normalizing it, but that did not help. Thank you in advance!

Take care,
Malte
