WEDGE_FELIPPA_RULE
Quadrature Rules for the Wedge


WEDGE_FELIPPA_RULE is a MATLAB library which generates quadrature rules to estimate integrals 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
