| 摘 要： | In this paper an error estimate is derived, if λ∈[0, 1], for tile lacunaryquartic C2-spline interpolant which interpolates the first derivative of a given smooth function at the mesh points and as well as its second derivative at an arbitrary interior point between consecutive knots, if the mesh is uniform. Moreover, all application to quadratures is also presented. |
