| Oct 15, 2017 at 12:57 | comment | added | David Ketcheson | Ah -- I took your question to mean "is the number of local extrema of the spline interpolant less than or equal to the number of local extrema of $f$". If you mean something different, I think you should edit the question to be more specific. | |
