SYNOPSIS
SUBROUTINE CQCAI (LUN, KPRINT, IPASS)

NAME
cqcai - Quick check for SLATEC subroutines CAIRY, CBIRY

LIBRARY

CATEGORY
C10D

TYPE
COMPLEX (CQCAI-C, ZQCAI-Z)

KEYWORDS
QUICK CHECK, CAIRY, CBIRY

AUTHOR
Amos, Don, (SNL) Goudy, Sue, (SNL) Walton, Lee, (SNL)

DESCRIPTION
*Usage: INTEGER LUN, KPRINT, IPASS CALL CQCAI (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: CQCAI is a quick check routine for the complex Airy functions generated by subroutines CAIRY and CBIRY. CQCAI generates Airy functions and their derivatives from CAIRY and CBIRY and checks them against the Wronskian evaluation in the Z plane.
