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) See also : QPDOC Details : Documentation Fullsource Source Sites : (1) ARNO (2) ITL
