✦ Synopsis

In this paper a strategy is presented to construct a shape-preserving quasi-interpolant function expressed as a linear combination of quadratic splines with local support where the coefficients are given by the data. The quasi-interpolant is shown to be linear-reproducing, monotone and/or convex conforming to the data. (~) 1999 Elsevier Science B.V. All rights reserved.
