摘要:
This paper investigated the convergence of the parallel diagonals (with fixed difference of denominator degrees and numerator degrees) sequences of the rational interpolation to a Stieltjes function. A simple convergence criterion was given and conclusions about the position of poles were established. (C) 2003 Elsevier B.V. All rights reserved.
