A class of quaternion matrices called generalized η -(anti-)bi-Hermitian matrices is defined which incorporates the η -(anti-)bi-Hermitian matrices mentioned by Yuan et al. [Linear Multilinear Algebra. 63;2015:1849–1863] as special cases. In the earlier referred work, Yuan et al. have derived explicit formulas for the least-squares η -(anti-)bi-Hermitian solutions of the coupled matrix equations (AXB, CXD)=(E, F). In this paper, an efficient iterative algorithm is proposed to numerically find the generalized least-squares η -(anti-)bi-Hermitian solutions of the coupled matrix equations (Formula presented.) The validity and efficiency of the presented algorithm is examined by some test experiments.
