Description
Abstract:	This paper investigates some aspects of discrete least squares approximation by translates of certain classes of radial functions. Its specific aim is (i) to provide conditions under which the associated least squares matrix is invertible, and (ii) to give upper bounds for the Euclidean norms of the inverses of these matrices (when they exist).
