摘要
Let R is an element of R-nxn be a nontrivial symmetric involution, i.e., R-2 = I, R-T = R not equal +/-I. A is an element of C-nxn is said to be R - conjugate if (A) over bar = RAR. In this paper, necessary and sufficient conditions are established for the existence of and the expression for the R - conjugate solution to the matrix equations AX = C and XB = D. Furthermore, the explicit expression of the solution to the corresponding optimal approximation problem is obtained.
