D01ATF

 
Is a general-purpose integrator which calculates an approximation to the
integral of a function F(x) over a finite interval (A,B): I = the integral from A to B
of F(x)dx.
 
Classes  :  H2a1a1 . Automatic 1-D finite interval quadrature (user need only
                   specify required accuracy), integrand available via
                   user-defined procedure
 
Type     : Fortran subroutine in NAG library (D01 sublibrary).
Access   : Proprietary. Many implementations available.
Precision: Double.
 
Usage    : CALL D01ATF(F, A, B, EPSABS, EPSREL, RESULT, ABSERR, W, LW, IW, LIW,
           IFAIL)
