*DECK AIE FUNCTION AIE (X) C***BEGIN PROLOGUE AIE C***PURPOSE Calculate the Airy function for a negative argument and an C exponentially scaled Airy function for a non-negative C argument. C***LIBRARY SLATEC (FNLIB) C***CATEGORY C10D C***TYPE SINGLE PRECISION (AIE-S, DAIE-D) C***KEYWORDS EXPONENTIALLY SCALED AIRY FUNCTION, FNLIB, C SPECIAL FUNCTIONS C***AUTHOR Fullerton, W., (LANL) C***DESCRIPTION C C AIE(X) computes the exponentially scaled Airy function for C non-negative X. It evaluates AI(X) for X .LE. 0.0 and C EXP(ZETA)*AI(X) for X .GE. 0.0 where ZETA = (2.0/3.0)*(X**1.5).
