MINRES-QLP: a Krylov subspace method for indefinite or singular symmetric systems

Sou-Cheng T. Choi, Christopher C. Paige, Michael A. Saunders

CG, SYMMLQ, and MINRES are Krylov subspace methods for solving symmetric systems of linear equations. When these methods are applied to an incompatible system (that is, a singular…
