【摘要】 借助于矩阵的奇异值分解及矩阵的广义逆 ,给出了矩阵方程AX =B ,XC =D及AXB =D有对称正定解的充分必要条件 ,并在有解的情况下 ,给出了通解的显式表示。
【Abstract】 A necessary and sufficient condition for matrix equations AX=B, XC=D and AXB=D to have symmetric positive definite solutions is obtained by using SVD and generalized inverses of matrices, and the explicit representation of general solutions is also given.
