CUBE_FELIPPA_RULE
Quadrature Rules for a Cube in 3D


CUBE_FELIPPA_RULE is a C library which generates the points and weights of a Felippa quadrature rule over the interior of a cube in 3D.

Actually, the word "cube" is meant to designate any quadrature region defined by:

        A(1) <= X <= B(1)
        A(2) <= Y <= B(2)
        A(3) <= Z <= B(3)
