SpletA is an invertible matrix, one of the two real numbers TrB 1 and TrB 2 is nonzero. Without loss of generality, we may assume that TrB 1 6= 0. Hence A 1 is the real linear combination of ˆ A and A 2. Applying the combination to (4), we obtain that ˆ AB = ˆ A 0B0 1 + A 2 B 2. Because ˆ A is invertible, we can nd an invertible matrix Ssuch ...
