| 1 |
\boldsymbol{A}^\mathrm{T} |
$\boldsymbol{A}^\mathrm{T}$ |
$\times$ |
| 2 |
\boldsymbol{A}^\top |
$\boldsymbol{A}^\top$ |
$\times$ |
| 3 |
\boldsymbol{A}^\mathsf{T} |
$\boldsymbol{A}^\mathsf{T}$ |
$\surd$ |
| 4 |
\boldsymbol{A}^\intercal |
$\boldsymbol{A}^\intercal$ |
$\surd$ |
3 或 4 都可, 我平常使用 3.
举个例子
设 $\boldsymbol{M} = \boldsymbol{A}^\mathsf{T}\boldsymbol{A}$, 则
$$
\boldsymbol{M}^\mathsf{T} = (\boldsymbol{A}^\mathsf{T}\boldsymbol{A})^\mathsf{T} =
\boldsymbol{A}^\mathsf{T}\boldsymbol{A} = \boldsymbol{M}
$$
所以 $\boldsymbol{M}$ 是对称矩阵.
