dc.description.abstract | The estimation of the quadrature error of a Gauss quadrature rule when applied to the
approximation of an integral determined by a real-valued integrand and a real-valued
nonnegative measure with support on the real axis is an important problem in scientific
computing. Laurie [2] developed anti-Gauss quadrature rules as an aid to estimate this error.
Under suitable conditions the Gauss and associated anti-Gauss rules give upper and lower
bounds for the value of the desired integral. It is then natural to use the average of
Gauss and anti-Gauss rules as an improved approximation of the integral. Laurie also
introduced these averaged rules. More recently, the author derived new averaged Gauss
quadrature rules that have higher degree of exactness for the same number of nodes as the
averaged rules proposed by Laurie. In [2], [5], [3] stable numerical procedures for
computation of the corresponding averaged Gaussian rules are proposed. An analogous
procedure can be applied also for a more general class of weighted averaged Gaussian rules
introduced in [1]. Those results are presented in [4]. Here we we give a survey of the quoted
results, which are obtained jointly with L. Reichel (Kent State Univ., OH (U.S.)) | sr |
