摘要：

Algorithms for computing the logarithm of Bessel functions of complex argument and fractional order are presented. These algorithms will be useful when direct evaluation of the Bessel function causes computer overflow or underflow. Several numerical results are presented, and an example of electromagnetic scattering by a conducting wedge is given. Copyright (C) 2006 John Wiley & Sons, Ltd.
