摘要
本文研究以Laguerre正交多项式的零点为基点的Grunwald型插值过程R_n(f,x)=sum from(k=0)to n(f(x_k)r_J(x)),0≤x<+∞逼近无界函数f(x)的阶,这是作者工作〔1〕的继续.
This paper gives an account on the degree of approximating unbo- unded function f(x) by Grunwald type interpolation process Rn(f,d) Which is based on the zeros of Laguerre orthrgrnal polynomials L_n(x) Ⅱ L_n-(x)
