Abstract : Subroutines have been written in FORTRAN for the CDC 3600/3800 to evaluate Bessel Functions of the first and second kinds for integer or half odd-integer orders and positive real arguments. (J sub n)(x),(Y sub n(x) (x), (j sub n)(x), and (y sub n)(x) have been checked for values of n as small as 0 and as large as 5000 and for values of x as small as 0.0001 and as large as 4000.
