(van Barel, Marc)
A look-ahead method for computing vector Padé-Hermite approximants. (English)
[J] Constructive Approximation 11, No.4, 455-476 (1995). ISSN 0176-4276; ISSN 1432-0940/e

Summary: We present an algorithm to compute vector Padé-Hermite approximants along a sequence of perfect points in the vector Padé Hermite table. We show the connection to matrix Padé approximants. The algorithm is used to compute the solution of a block Hankel system of linear equations.
