    13 pages, no figures.-- MSC2000 codes: 33C47, 42C05.MR#: MR2480082Zbl#: Zbl pre05602092In the present paper, we obtain quadrature rules for Bernstein measures on [-1, 1], having a fixed number of nodes and weights such that they exactly integrate functions in the linear space of polynomials with real coefficients.The first three authors were partially supported by Ministerio de Educación y Ciencia under grant number MTM2005-01320.

    Error bound of certain Gaussian quadrature rules for trigonometric polynomials

    Get PDF
    In this paper we give error bound for quadrature rules of Gaussian type for trigonometric polynomials with respect to the weight function w(x) = 1+cos x, x ∈ (−π, π), for 2π -periodic integrand, analytic in a circular domain. Obtained theoretical bound is checked and illustrated on some numerical examples
