چکیده

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 a generalized $(p,q)$-reflexive matrix $x$‎, ‎a‎ ‎generalized $(p,q)$-reflexive solution can be obtained within finite iteration‎ ‎steps in the absence of roundoff errors‎, ‎and the least frobenius norm‎ ‎generalized $(p,q)$-reflexive solution can be obtained by choosing an‎ ‎appropriate initial iterative matrix‎. ‎furthermore‎, ‎the optimal approximate‎ ‎generalized $(p,q)$-reflexive solution to a given matrix $x_{0}$ can be‎ ‎derived by finding the least frobenius norm generalized $(p,q)$-reflexive‎ ‎solution of a new corresponding quaternion matrix equation‎. ‎finally‎, ‎two‎ ‎numerical examples are given to illustrate the efficiency of the proposed methods‎.

An Efficient Algorithm for the Reflexive Solution of the Quaternion Matrix Equation AXB + CXHD = F

We propose an iterative algorithm for solving the reflexive solution of the quaternion matrix equation AXB + CXHD = F. When the matrix equation is consistent over reflexive matrix X, a reflexive solution can be obtained within finite iteration steps in the absence of roundoff errors. By the proposed iterative algorithm, the least Frobenius norm reflexive solution of the matrix equation can be d...

Gradient Based Iterative Algorithm for Solving the Generalized Coupled Sylvester-transpose and Conjugate Matrix Equations over Reflexive (anti-reflexive) Matrices

Linear matrix equations play an important role in many areas, such as control theory, system theory, stability theory and some other fields of pure and applied mathematics. In the present paper, we consider the generalized coupled Sylvestertranspose and conjugate matrix equations Tν(X) = Fν , ν = 1, 2, . . . , N, where X = (X1, X2, . . . , Xp) is a group of unknown matrices and for ν = 1, 2, . ...

The least-square bisymmetric solution to a quaternion matrix equation with applications

In this paper, we derive the necessary and sufficient conditions for the quaternion matrix equation XA=B to have the least-square bisymmetric solution and give the expression of such solution when the solvability conditions are met. Futhermore, we consider the maximal and minimal inertias of the least-square bisymmetric solution to this equation. As applications, we derive sufficient and necess...
