✦ Synopsis
Communicated by A. Kunoth
Quasi-interpolation is very important in the study of the approximation theory and applications. In this paper, a multilevel univariate quasi-interpolation scheme with better smoothness using cubic spline basis on uniform partition of bounded interval is proposed. Moreover, its application to numerical integration is presented. Furthermore, some examples are given and show that the presented method is easy and valid.
