A numerical algorithm for computing the zeros of parabolic cylinder functions in the complex plane

T. M. Dunster, A. Gil, D. Ruiz-Antolín +1

A numerical algorithm (implemented in Matlab) for computing the zeros of the parabolic cylinder function $U (a, z)$ in domains of the complex plane is presented. The algorithm uses a…

Uniform asymptotic expansions for the zeros of parabolic cylinder functions

T. M. Dunster, A. Gil, D. Ruiz-Antolin +1

The real and complex zeros of the parabolic cylinder function $U (a, z)$ are studied. Asymptotic expansions for the zeros are derived, involving the zeros of Airy functions, and thes…
