The other matrices mentioned by Christian that appear in the computation of the determinant are named only in one script (all other texts either don't give a name at all, or call it A~ or something like that), where they are called the algebraic complement. Perhaps in the US (I'm in Switzerland) the usage of the term differs from Europe. However, it seems that Christian is from Germany ... Regards, Andor
