Abstract
Because the Lagrange interpolation polynomial does not converge uniformly for an arbitrary continous function, two new operators Un(f;x) and n(f;x) are constructed,based on x(n)k=(2k+1)/(2n+1)π (k=0,1,…,2n) as the interpolation nodes and the best convergence order of them are better than An(f;x),Bn(f;x),Cn(f;x).关键词
