Taking into account that the Bernstein–Szegö measures are very suitable for approximating an important class of measures we also present a quadrature formula for this type of measures such that the error can be controlled with a well-bounded formula.application/pdfeng© SpringerOrthogonal polynomialsSzegö quadratureNumerical integrationresearch articleMatemáticas10.1007/s11075-007-9121-3open access
