Partial shape preserving approximations by bivariate Shepard operators
Abstract
Extending the results from the univariate case in a paper by Gal and Szabados, in this paper, we prove that the bivariate Shepard interpolation operators preserve the monotonicity and the convexity of bivariate functions in neighborhoods of some points. © 2001 Elsevier Science Ltd.
