DESCRIPTION
*Usage: INTEGER LUN, KPRINT, IPASS CALL CQCBK (LUN, KPRINT, IPASS) *Arguments: LUN :IN is the unit number to which output is to be written. KPRINT :IN controls the amount of output, as specified in the SLATEC Guidelines. IPASS :OUT indicates whether the test passed or failed. A value of one is good, indicating no failures. *Description: CQCBK is a quick check routine for the complex K Bessel function generated by subroutine CBESK. CQCBK generates sequences of I and K Bessel functions from CBESI and CBESK and checks them against the Wronskian evaluation in the (Z,FNU) space.
