Singular constrained linear systems
M. Nikuie, Mirkamal Mirnia · International journal of industrial mathematics. · 2013
In the linear system Ax = b the points x are sometimes constrained to lie in a given subspace S of column space of A. Drazin inverse for any singular or nonsingular matrix, exist and is unique. In this paper, the singular consistent or inconsistent constrained linear systems are introduced and the eect of Drazin inverse in solving such systems is investigated. Constrained linear system arise in electrical network theory.
