The Estimates of the Hermite-Fejer Inter Polation with the Second Kind |
| |
Abstract: | Let Hn ( f, x ) . Qu ( f, x ) . Rn ( f, x ) be H- F. quasi H- F. extensive H-F interpolation polynomials, respectively. Which are based on the zeros bk of the chebyshev polynomial Un ( x ) . Suppose thatf(x) ∈C' -l, 1]. we obtain the corresponding results the asymp -totic estimates. |
