Webi(AA ), so for a positive semidefinite matrix A, we have s i(A) = i(A) (i =1;2;:::;n). The trace functional of A 2M n(C), denoted by tr A or tr(A), is defined to be the sum of the entries on the main diagonal of A and it is well known that the trace of a matrix A is equal to the sum of its eigenvalues, that is, tr A = P n j=1 j(A).
