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.
