in the present paper, we propose an iterative algorithm for solving the generalized $(p,q)$-reflexive solution of the quaternion matrix equation $overset{u}{underset{l=1}{sum}}a_{l}xb_{l}+overset{v} {underset{s=1}{sum}}c_{s}widetilde{x}d_{s}=f$. by this iterative algorithm, the solvability of the problem can be determined automatically. when the matrix equation is consistent over...
