Abstract
This paper describes computer subroutines which were developed to compute Bessel functions of the first and second kind (J_n (z) and Y_n (z), respectively) for a complex argument z and a range of integer orders. A novel way of determ ining the starting point of backward recurrence is used, and the algorithm for Y_n (z) improves on previous algorithms in terms of accuracy and restrictions on the range of orders.
Title of program: BESCJY
Catalogue Id: ACPH_v1_0
Nature of problem
Bessel functions arise in the mathematical solution of physical problems, formulated in cylindrical and spherical coordinate systems. The CBESJY subroutine computes Jn(z) and Yn(z) for complex argument z and a sequence of integer orders n from M to N, where N >= 1 and M <= 0.
