The reflexive and anti-reflexive unitary solutions to matrix equations AX=B and XC=D
For a given generalized reflection matrix P,the reflexive and anti-reflexive unitary solutions to matrix equa-tions AX=B and XC=D with respect to generalized reflection matrix P are investigated.By using singular value decomposi-tion and spectral decomposition of symmetric matrix,the explicit expressions for the constraint solutions mentioned above are obtained.Finally,numerical examples are presented to illustrate and explain our results.
