INT_GREEN3D_TRI and INT_GREEN3D_POLY are designed to analytically integrate the Green’s function and its gradient over plane faces in 3d. These functions implements the formulas in:
R. Graglia, "Numerical Integration of the linear shape functions times the 3-d Green's function or its gradient on a plane triangle", IEEE Transactions on Antennas and Propagation, vol. 41, no. 10, Oct 1993, pp. 1448--1455
They are intended to be used as kernel functions for the implementation of the boundary element method and other integral methods.
