Kragujevac J. Math. 24 (2002) 85-94. UNIVARIATE SHEPARD-LAGRANGE INTERPOLATIONRadu T. TrimbitasFaculty of Mathematics and Computer Science, "Babe s-Bolyai" University, Cluj-Napoca, Romania (Received July 15, 2002) Abstract. In this paper we study the univariate Shepard-Lagrange interpolation operator where (yn,k) are the interpolation nodes and (Lmf)(x;yn,k) is the Lagrange interpolation polynomial with nodes yn,k,yn,k+1,�,yn,k+m. Then we give error estimations for various distribution of interpolation nodes.
