This paper deals with the estimation of the quadrature error of a Gaussian formula for weight functions involving powers, exponentials and Bessel functions of the first kind. For this purpose, in this work the averaged and generalized averaged Gaussian rules are employed, together with a tentative a priori approximation of the error. The numerical examples confirm the reliability of these approaches.

Abstract
This paper deals with the estimation of the quadrature error of a Gaussian formula for weight functions involving powers, exponentials and Bessel functions of the first kind. For this purpose, in this work the averaged and generalized averaged Gaussian rules are employed, together with a tentative a priori approximation of the error. The numerical examples confirm the reliability of these approaches.File in questo prodotto:
