在Filon型法和渐进法的基础上,构造了一类含有贝塞尔函数广义积分的一个有效数值算法,同时给出了新算法所产生的误差,并用数值算例对理论分析得结果进行了检验.理论分析及数值实验均表明:当参数r增大时,该算法的精确度将提高.
Based on Filon-type and Asymptotic method, this paper constructs an efficient numerical method for evaluating a class of generalized integrals involving Bessel functions and presents the asymptotic error of the new method. Theoretical analysis and experimental results show that the accuracy of this method increases with the parameter r.
