%X In this paper, we
propose DQMR algorithm for the Drazin-inverse solution of con<span>sistent or inconsistent linear systems of the form <i>Ax</i>=<i>b</i> where <img src=\"Edit_ceafb03d-3fc3-493c-a025-7fbfd699833b.bmp\" alt=\"\" />&nbsp;is a&nbsp;singular and in general non-hermitian matrix that has an arbitrary index. DQMR
algorithm for singular systems is analogous to QMR algorithm for non-singular
systems. We compare this algorithm with DGMRES by numerical experiments.</span>
