有限数学示例

⎡ ⎢ ⎣ \begin{matrix} 1 & 4 & - 2 & 21 3 & - 6 & - 3 & - 18 2 & 4 & 1 & 37 \end{matrix} ⎤ ⎥ ⎦

$[\begin{array}{c} 1 & 4 & - 2 & 21 \\ 3 & - 6 & - 3 & - 18 \\ 2 & 4 & 1 & 37 \end{array}]$

解题步骤 1

Transpose the matrix by switching its rows to columns.

⎡ ⎢ ⎢ ⎢ ⎢ ⎣ \begin{matrix} 1 & 3 & 2 4 & - 6 & 4 - 2 & - 3 & 1 21 & - 18 & 37 \end{matrix} ⎤ ⎥ ⎥ ⎥ ⎥ ⎦

$[\begin{array}{c} 1 & 3 & 2 \\ 4 & - 6 & 4 \\ - 2 & - 3 & 1 \\ 21 & - 18 & 37 \end{array}]$
