Error estimates for a Gaussian rule involving Bessel functions (2301.11738v1)
Published 27 Jan 2023 in math.NA and cs.NA
Abstract: This paper deals with the estimation of the quadrature error of a Gaussian formula for weight functions involving fractional 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.
