逆(方阵) 小节,第 3 段

观察这个方阵,我们如果用另一个矩阵乘$A$,则得到的结果矩阵中的每一列应该都是【$\begin{bmatrix}1\2\end{bmatrix}$的倍数】,所以我们不可能从$AB$的乘积中得到单位矩阵$I$。

应该是 $\begin{bmatrix}1\\3\end{bmatrix}$的倍数

Gram-Schmidt正交化法 小节,倒数第 2 段

* 单位化,$q_1=\frac{1}{\sqrt 3}\begin{bmatrix}1\1\1\end{bmatrix},\quad 【q_2=\frac{1}{\sqrt 2}\begin{bmatrix}1\0\2\end{bmatrix}$】...

应该是 q_2=\frac{1}{\sqrt 2}\begin{bmatrix}0\\-1\\1\end{bmatrix}$
