In this paper,we study the least squares solutions to matrix equations AX=B and XC=D with reflexive and anti-reflexive orthogonal constraints with respect to generalized reflection matrix.By using singular value decomposition,we establish the explicit expressions for the constraint solutions mentioned above.Finally,numerical examples are tested to illustrate the accuracy of our results.
