Hi Mark, The docs you linked reference https://epubs.siam.org/doi/10.1137/0720057 which is gated, so only an impression: this seems to construct a shape-preserving piecewise quadratic interpolant. We have two shape-preserving cubic interpolants, PCHIP and Akima. Do you have an overview of how this one compares to them? Off the cuff, I guess we can add a shape-preserving quadratic, too. This should be based on either BSpline or PPoly, depending on the basis the construction is in. (My impression is that it's the latter in the R package). The API should mirror that of Akima1DInterpolator. пт, 10 мая 2019 г., 9:45 Mark Mikofski <mikofski@berkeley.edu>:
Hi All,
Sorry for this unresearched and inexperienced question.
Does anyone have any experience with the "Schumaker quadratic spline" for 1-D interpolation? Is it similar enough to the BSpline already in SciPy?
I have some source code that I can contribute if there's interest.
As far as references, a google search turned up an R function: * https://cran.r-project.org/web/packages/schumaker/vignettes/schumaker.html
