Notes

bessel_j_seq_complex evaluates a sequence of values for the Bessel function of the first kind , where is complex and nonzero and is the order with . The -member sequence is generated for orders when . Note that is replaced by when . For positive orders the function may also be called with , since when . For negative orders the formula

is used to generate the required sequence. The appropriate values of and are obtained by calls to bessel_j_complex() and bessel_y_complex().
