Quasi-interpolants Based on Trigonometric Splines
作者： Tom Lyche , Larry L. Schumaker , Sonya Stanley
关键词:
摘要: A general theory of quasi-interpolants based on trigonometric splines is developed which analogous to the polynomial spline case. The aim construct are local, easy compute, and apply a wide class functions. As examples, we give detailed treatment including error bounds for two classes especially useful in practice.
