Interpolation by Pure Radial Sums

by M. Buhmann and F. Derrien and A. Le Méhauté

(Report number 1995-02)

Abstract
We investigate some asymptotic spectral properties of the collocation matrix arising in interpolation by pure radial sums, and we provide some theoretical results that can be used for knot removal.
