An n×n real matrix P is said to be a symmetric orthogonal matrix if P = P −1 = P T . An n×n real matrix Y is called a generalized centro-symmetric with respect to P, if Y = PYP. It is obvious that every matrix is also a generalized centrosymmetric matrix with respect to I. In this work by extending the conjugate gradient approach, two iterative methods are proposed for solving the linear matrix equation
