Splines with Non-Negative B-Spline Coefficients,
Abstract
The authors consider the question of the approximation of non-negative functions by non-negative splines of order k (degree <k) compared with approximation by that subclass of non-negative splines of order k consisting of all those whose B-spline coefficients are non-negative; while approximation by the former gives errors of order R sub K), the latter may yield only (h sup 2). These results are related to certain facts about quasi-interpolants. (Author)
