This paper introduces the notion of apower Hermite Padé approximant, a generalization of the classical scalar Hermite Padé approximant. We show that this generalized form provides a unifor approach for different concepts of matrix-type Padé approximants. This includes descriptions of vector and matrix Padé approximants along with generalizations of simultaneous and Hermite Padé approximants. A complete description of these new approximants, based on the characterization of a corresponding… CONTINUE READING
