数学3.一道高代题
\(A= \left( \begin{array}{ccc}
a_1 & b_1 & c_1 \\
d_1 & e_1 & f_1 \\
g_1 & h_1 & i_1 \end{array} \right)\)
\(B= \left( \begin{array}{cc}
a_2 & b_2 \\
d_2 & e_2 \\
\end{array} \right)\)
\(C= \left( \begin{array}{cc}
a_3 & b_3 \\
d_3 & e_3 \\
g_3 & h_3 \end{array} \right)\) 为三个已知矩阵,不可逆。\(X_{3\times 2}\)为未知矩阵。
求解方程\( AX+XB=C \)
一般规律是什么?
