And when the matrix equations have a Solution or have an unique solution, the expression of the solution has been presented. Key Words: Fundamental transformation; QR decomposition; Singular value decomposition; matrix equation.目 录1引言12矩阵的两种分解1 2.1 QR分解22.2 奇异值分解23 AX=B的解法 4 3.1矩阵 可逆6 3.2 矩阵 为满秩矩阵7 3.3 不可逆7 3.4典型题举例74 AXB=C的解法 12 4.1 若 , 均可逆14 4.2 若 ( )可逆, ( )不可逆14 4.3 若 , 均不可逆14 4.4 典型题举例145结束语186参考文献19【包括:毕业论文、开题报告、任务书】【说明:论文中有些数学符号是编辑器编辑而成,网页上无法显示或者显示格式错误,给您带来不便请谅解。】
