Abstract
Presents some basic principles of the solution of large systems of simultaneous linear equations by sparsity methods, particularly Zollenkopf´s bifactorisation method, and describes diakoptics (Gabriel Kron´s method of tearing). Implications of these two approaches, used together, are discussed with particular reference to system optimization and finite-element analysis of nonlinear and large problems.
