摘要
给出了计算虚阶Ｂｅｓｓｅｌ函数及其导数的完整算法．数值结果表明，计算精度可达１０位以上有效数字．此外，所给出的逆推法可推广到复阶数的情形．
An integrated algorithm is presented for the computation of Bessel functions of imaginary orders and their derivatives. The numerical results show that the accuracy of the algorithm is more than 10 significant digits. In addition, the backward recurrence algorithm given can be extended to the one of complex orders.
