Calculates an approximation to the Hilbert transform of a function G(x) over (A, B), i.e., the integral of G(x)/(x-C) over (A,B), for user-specified values of A,B,C. 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 NAG library (D01 sublibrary). Access : Proprietary. Many implementations available. Precision: Double. Usage : CALL D01AQF (G, A, B, C, EPSABS, EPSREL, RESULT, ABSERR, W, LW, IW, LIW, IFAIL) Details : Documentation Example Example-output Sites : (1) AIX (2) ITL
