QAGI

 
Automatic adaptive integrator for semi-infinite or infinite intervals. Uses
nonlinear transformation and extrapolation.
 
Classes  :  H2a3a1 . Automatic 1-D semi-infinite interval quadrature (user
                   need only specify required accuracy) (including exp(-x)
                   weight function), integrand available via user-defined
                   procedure
            H2a4a1 . Automatic 1-D infinite interval quadrature (user need
                   only specify required accuracy) (including exp(-x**2)
                   weight function), integrand available via user-defined
                   procedure
