摘　　要：本文介绍了复宗量整数阶圆柱函数数值计算的递推算法。在计算机允许的数值范围内对圆柱函数的阶数及宗量范围均没有限制。试算结果经加法定理和Wronskian关系式的验算表明准确度很高。Numrtical computation of Bessel function with integer orders for complex argument depends seriously on the acquired sophisticated algorithm. A recurrence algorithm is presented in this paper. The high accuracy of this algorithm were verified by examining the mumerical error in the Wronskian's and the Neumann's additional theorem.
