| Abstract: | The purpose of this paper is to discuss the problem of bivariate cardinal interpolation by box splines and their derivatives on a three-direction regular mesh on R~2. We improve and generalize the results given by de Boor,H(?)lling and the others,and in particular give the convergence and the error estimation of this cardinal interpolation as the degree tends to inhnity. |
