within this paper we make a comparison in terms of performances between the GMRES method and the K equivalent real formulation, when both applied to the solution of complex linear systems like Cz = γ.

Everything is verified over a set of matrices coming out from discretization via MoM of the electrical field integral equation in the electromagnetic scattering by an ideal electric conductor.

Abstract
within this paper we make a comparison in terms of performances between the GMRES method and the K equivalent real formulation, when both applied to the solution of complex linear systems like Cz = γ. As well we point out how performances grow worse passing from complex to real arithmetics, except that C fulfills suitable conditions. Everything is verified over a set of matrices coming out from discretization via MoM of the electrical field integral equation in the electromagnetic scattering by an ideal electric conductor.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
