Padé approximation and its applications location:Antwerp date:4-6 April 1979
W. B. Gragg has given a connection between the Viskovatoff algorithm for
determination of continued fractions and the triangular factorisation of
In this paper, this idea will be further develloped to include most of the known
recursive algorithms for the computation of Padé approximants.
The factorization interpretation links together the continued fraction approach and the recursive Padé computation in a natural way.
