| Abstract: | A method for calcuating the values of modified Bessel functions with integer orders and complex arguments(i.e.I n(z) and K n(z)) is presented in terms of I n(z) and K n(z) vaying with n?when z is fixed.For I n(z),backward recurrence is used;for K n(z),forward recurrence is used.It has been proved that the method is a quick and rigorous algorithm. |
