Abstract
In this paper, we establish some necessary and sufficient conditions for the solvability to a system of five quaternion matrix equations in terms of the Moore–Penrose inverse and the rank of a matrix, and give an expression of the general solution to the system when it is consistent. As an application, we investigate an \(\eta \)-Hermicity solution of a system. Moreover, we present a numerical example to illustrate the main results of this paper.
