Green's function formulae for the internal intensity in radiative transfer computations by matrix-vector methods

In radiative transfer computations, Green's functions are particularly useful and have a straightforward physical interpretation, as discussed by Cogley and co-workers. By recognizing that, in thermal emission problems, the angular distribution of emission is prescribed a priori, one can obtain a more rapid computational procedure in which most computations are in discrete formalism one-dimensional or vector formulae.
