“…For instance, by using the matrix decompositions such as the singular value decomposition (SVD), generalized singular value decomposition (GSVD), and canonical correlation decomposition of matrices (CCD), the matrix equation AXB + CY D = E have been considered by Chu [8], Xu, Wei, and Zheng [9], Shim and Chen [10] and Liao, Bai and Lei [11], etc. More recently, some efficient iterative methods, including Smith-type iterative algorithm, gradient iterative (GI) algorithm, LSQR iterative method, conjugate gradient (CG) method, generalized QMRCGSTAB algorithm and so forth, were introduced for solving various linear matrix equations [12][13][14][15][16][17][18][19][20][21][22][23][24].…”
