WEDGE_INTEGRALS
Integrals Inside the Unit Wedge in 3D


WEDGE_INTEGRALS is a FORTRAN90 library which returns the exact value of the integral of any monomial x^i y^j z^k over the interior of the unit wedge in 3D.

The interior of the unit wedge in 3D is defined by the constraints:

        0 <= X
        0 <= Y
             X + Y <= 1
       -1 <= Z <= +1
