摘要
研究了 Bernstein插值多项多 Hn(f ;x)对 Cj[- 1 ,1 ,] (1≤ j≤ 3)连续函数类的逼近阶 。
The convergence order of a new polynomial operator Hn(f:x) approximate to f(x) is a member of the set of C[-1,1]j, (0 [less-than or equal to] j [less-than or equal to] 3) is studied. The convergence order relative to dots is obtained.
