带Legendre多项式零点的Grünwald插值过程的平均收敛阶

Average Convergence Order in Interpolation by Grünwald Polynomial with Zeros of Legendre Polynomial

给出了具Ｌｅｇｅｎｄｒｅ多项式零点的Ｇｒüｎｗａｌｄ插值过程的平均收敛阶。

Determination of the average convergence order by Grünwald interpolatory polynomial G 2n-1 (f,x) with zeros of Legendre polynomial is given in this paper.Study result shows that the convergence order has achieved optimum.
