D01DAF

 
Attempts to evaluate a double integral to a specified absolute accuracy by
repeated applications of the method described by Patterson.
 
Classes  :  H2b1a1 . Automatic n-D quadrature (user need only specify required
                   accuracy) on one or more hyper-rectangular regions,
                   integrand available via user-defined procedure
 
Type     : Fortran subroutine in NAG library (D01 sublibrary).
Access   : Proprietary. Many implementations available.
Precision: Double.
 
Usage    : CALL D01DAF (YA, YB, PHI1, PHI2, ABSACC, ANS NPTS, IFAIL)
 
Details  : Documentation Example Example-output
Sites    : (1) AIX (2) ITL
