Abstract
Let be the set of all
matrices over the real quaternion algebra.

is
-bihermitian, if
. We in this paper, present the solvability conditions and the general
-Hermitian solution to a system of linear real quaternion matrix equations. As an application, we give the necessary and sufficient conditions for the system
to have an
-bihermitian solution. We establish an expression of the
-bihermitian to the system when it is solvable. We also obtain a criterion for a quaternion matrix to be
-bihermitian. Moreover, we provide an algorithm and a numerical example to illustrate the theory developed in this paper.
