NAME

DESCRIPTION
*Usage: INTEGER LUN, KPRINT, IPASS CALL CQCBI (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: CQCBI is a quick check routine for the complex I Bessel function generated by subroutine CBESI. CQCBI generates sequences crossing formula boundaries which are started by one formula and terminated in a region where another formula applies. The terminated value is checked by the formula appropriate to that region.
