Needless to say, our native spline support doesn't seem to have this. Is there any subpart of Sage that does?

https://ask.sagemath.org/question/10499/spline-smoothing-parameter/?comment=17078#post-id-17078Although for extra credit, I would like to have a formula connecting `s` with the `alpha` in the Matlab doc. The overall relationship is clear from the Scipy terminal doc, but I'm not sure there is an exact correspondence.Tue, 03 Sep 2013 03:06:46 -0500https://ask.sagemath.org/question/10499/spline-smoothing-parameter/?comment=17078#post-id-17078
