We present a density matrix formulation of the spin-polarized Hartree-Fock method. The Hartree-Fcck density matrix equation is generalized to treat open-shell systems that can be described by a single determinant. The "eigenmatrix" equation breaks up into two equations, one for the density matrix de
We show how Van Loan's method for annulling the (2,1) block of skew-Hamiltonian matrices by symplecticorthogonal similarity transformation generalizes to general matrices and provides a numerical algorithm for solving the general quadratic matrix equation: For skew-Hamiltonian matrices we find thei
