A note on solving EP inconsistent linear systems

In this note we reconsider the problem posed in [S.L. Zhang, Y. Oyanagi, M. Su-gihara, Necessary and sufficient conditions for the convergence of Orthomin(k) on singular and inconsistent linear systems, Numer. Math. 87 (2000) 391-405], we give a stopping criterion for the iterative methods to EP inconsistent linear systems.
