A Sylvester-Type Matrix Equation over the Hamilton Quaternions with an Application [PDF]

open access: yesMathematics, 2022
We derive the solvability conditions and a formula of a general solution to a Sylvester-type matrix equation over Hamilton quaternions. As an application, we investigate the necessary and sufficient conditions for the solvability of the quaternion matrix

A New Solution to the Matrix Equation X−AX¯B=C [PDF]

open access: yesThe Scientific World Journal, 2014
We investigate the matrix equation X−AX¯B=C. For convenience, the matrix equation X−AX¯B=C is named as Kalman-Yakubovich-conjugate matrix equation. The explicit solution is constructed when the above matrix equation has unique solution. And this solution
