DQAWCE

 
The routine calculates an approximation result to a CAUCHY PRINCIPAL VALUE I =
Integral of F*W over (A, B) (W(X) = 1/(X-C), (C.NE.A, C.NE.B), hopefully
satisfying following claim for accuracy ABS(I-RESULT).LE.MAX(EPSABS,
EPSREL*ABS(I)).
 
Classes  :  H2a2a1 . Automatic 1-D finite interval quadrature (user need only
                   specify required accuracy) (special integrand including
                   weight functions, oscillating and singular integrands,
                   principal value integrals, splines, etc.), integrand
                   available via user-defined procedure
            J4 .     Hilbert transforms
 
Type     : Fortran subroutine in SLATEC library.
Access   : Public domain. Portable.
Precision: Double.
 
Usage    : CALL DQAWCE (F, A, B, C, EPSABS, EPSREL, LIMIT, RESULT, ABSERR,
           NEVAL, IER, ALIST, BLIST, RLIST, ELIST, IORD, LAST)
