The original (infinite integration range is mapped onto the interval (0, 1) and (A, B) is a part of (0, 1). it is the purpose to compute I = Integral of transformed integrand over (A, B), J = Integral of ABS(Transformed Integrand) over (A, B). Classes : H2a3a2 . Nonautomatic 1-D semi-infinite interval quadrature (including exp(-x) weight function), integrand available via user-defined procedure H2a4a2 . Nonautomatic 1-D infinite interval quadrature (including exp(-x**2) weight function), integrand available via user-defined procedure Type : Fortran subroutine in SLATEC library. Access : Public domain. Portable. Precision: Double. Usage : CALL DQK15I (F, BOUN, INF, A, B, RESULT, ABSERR, RESABS, RESASC) See also : QPDOC Details : Documentation Fullsource Source Sites : (1) ARNO (2) ITL
