Numerical and Asymptotic Aspects of Parabolic Cylinder Functions | Nico M. Temme
; | Date: |
24 Sep 2001 | Journal: | J. Comput. Appl. Math. 121 (2000) 221-246 | Subject: | Classical Analysis and ODEs; Numerical Analysis MSC-class: 33C15, 41A60, 65D20 | math.CA math.NA | Abstract: | Several uniform asymptotics expansions of the Weber parabolic cylinder functions are considered, one group in terms of elementary functions, another group in terms of Airy functions. Starting point for the discussion are asymptotic expansions given earlier by F.W.J. Olver. Some of his results are modified to improve the asymptotic properties and to enlarge the intervals for using the expansions in numerical algorithms. Olver’s results are obtained from the differential equation of the parabolic cylinder functions; we mention how modified expansions can be obtained from integral representations. Numerical tests are given for three expansions in terms of elementary functions. In this paper only real values of the parameters will be considered. | Source: | arXiv, math.CA/0109188 | Services: | Forum | Review | PDF | Favorites |
