Abstract
- In this paper we generalize the notion of orthogonal Laurent polynomials to orthogonal rational functions. Orthogonality is considered with respect to a measure on the positive real line. From this, Gauss-type quadrature formulas are derived and multipoint Pade´ approximants for the Stieltjes transform of the measure. Convergence of both the quadrature formula and the multipoint Pade´ approximants is discussed. [Copyright &y& Elsevier]
