Fast and accurate computation of Bessel functions with (large) complex order and argument

Abstract

A fast and highly accurate computational scheme to compute a product of Bessel functions with (large) complex order and argument is of utmost importance in some problems in physics involving cylindrical configurations. Since these products can occur in the kernel of multiple integrals, and are subject to mutual cancellations, speed and accuracy of their… (More)
