摘要
本文对二元Thiele型连分式的渐近分式施行Samelson逆变换,建立了平面矩形域上的二元向量值有理插值,所得结果是一元向量值有理插值的推广和改进.
In this paper, we show explicitly that by making use of the convergence of Thiele-type bran-ched continued fractions for two-variable functions, the samelson inverse may be used to definebivariate vector-valued rational interpolants. Our results are extensions and improvements of thosefor the one-variable case given in [1] and [2].
