This paper is concerned with double sequences={} of Hermitian matrices with complex entries∈) and formal Laurent series()=−Σ and()=Σ. Making use of a Favard-type theorem for certain sequences of matrix Laurent polynomials which was obtained previously in [1] we can establish the relation between the matrix counterpart of the so-called-fractions and matrix orthogonal Laurent polynomials. The connection with two-point Padé approximants to the pair (,) is also exhibited proving that such approximants are Hermitian too. Finally, error formulas are also given. |
