SQUARE_FELIPPA_RULE
Quadrature Rules for a Square in 2D


SQUARE_FELIPPA_RULE is a C++ library which generates the points and weights of a Felippa quadrature rule over the interior of a square in 2D.

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

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