## Abstract The direct methods for the solution of systems of linear equations with a symmetric positiveβsemidefinite (SPS) matrix __A__ usually comprise the Cholesky decomposition of a nonsingular diagonal block **A**~π₯~π₯ of **A** and effective evaluation of the action of a generalized inverse of
