Questions for spline coefficients calculation

[ghost]

Hello,

Sorry to pose a question in the issues section. I wonder if you may have the reference on how you calculated the spline coefficients in function _fit_open(pts)? It looks like the points are interpolated with parameters from [0,1] to form the cubic spline. I'm trying to interpolate a set of points with parameters from a given interval [0,c] (c>0). I wonder if you may have any thoughts?

Any help would be appreciated.

Thank you for making this repo public.
