For my own needs, I just ended a (smoothing) parametric Bspline class
that, through a matplotlib gui, let you :
- fitting a Bspline with the standard value of s=N-2sqrt(N) where N is
the number of sample of the data (measured in my case)
- change the value of the fitting parameter s
- modify manually the position of the knots and control points.
I'll post it in the next few days, after cleaning it.
Imho (and mainly in what I have read from Dierckx), the knots are the
values of the 1-D parameter and the control points may be N-D (so your
