摘要
讨论多元有理插值逼近问题 ,且证明它们的逼近阶为ωf( 1n) ,其中ωf( 1n)表示连续模 ,n表示矩形区域剖分竖直线的数目 .
The problem on multivariate rational interpolatory approximation is discussed.It is shown that the orders of approximation are ω f(1n) ,where the ω f(1n) is modulus of continuity,and n is the vertical line number of the segmentation at the rectangle.
