The recurrence method is useful for numerical calculation of the Bassel function Jv(x) of complex order v. The necessary total number of the recurrences in this method has been examined for the real order v, but it is known only for limited ranges of the real order v and the variable x, and it is not known for the complex order v. This letter proposes a new algorithm which increases the total number of the recurrences gradually, and which stops the calculation automatically when the approximate Bessel function with a necessary precision is obtained.
