An order O(2 n ) algorithm for computing all the principal minors of an arbitrary n Γ n complex matrix is motivated and presented, offering an improvement by a factor of n 3 over direct computation. The algorithm uses recursive Schur complementation and submatrix extraction, storing the answer in a
The principal components method enables component spectra from pigment mixtures to be estimated by evaluating the eigenvectors of the second moment matrix. The components are linear combinations of these eigenvectors, but cannot be identified unambiguously With the conditions of non-negativity of sp
