How to write matrix transpose(AT, Atr) in LaTeX?

Transpose matrix is ​​a mathematical symbol that different authors have identified in different ways in their books. E.g.

   \[ \mathbf{A}^T = \mathbf{A} \]
   \[ \mathbf{A}^\mathrm{T} = -\mathbf{A} \]
   \[ \mathbf{A}^\top = \overline{\mathbf{A}}\]
   \[ \mathbf{A}^\mathsf{T} = -\overline{\mathbf{A}} \]
   \[ \mathbf{A}^\mathsf{t},\; \mathbf{A}^\mathsf{tr}  \]

Output :

Transpose matrix in latex output.

This \top command is in multiple packages. And the shape is different from the default command.

   \[ \left[\mathbf{A}^\top\right]_{ij} = \left[\mathbf{A}\right]_{ji}\]
   \[ \begin{bmatrix}
      11 & 12\\
      13 & 14\\
      15 & 16    
   \end{bmatrix}^\top =
      11 & 13 & 15\\
      12 & 14 & 16    
   \end{bmatrix} \]

Output :

Use top command with MnSymbol package.

Use \intercal command for transpose matrix in LaTeX

You see more than one method at the point above but amssymb’s \intercal command is the best practice to represent the capital letter T.

   \[ (\mathbf{A}+\mathbf{B})^\intercal = \mathbf{A}^\intercal + \mathbf{B}^\intercal \]
   \[ (\mathbf{AB})^\intercal = \mathbf{B}^\intercal\mathbf{A}^\intercal \]
   \[ (c\mathbf{A})^\intercal = c\mathbf{A}^\intercal \]

Output :

Use amssymb package for transpose.

Power of transpose matrix

Symbols have been defined in different ways in different books to use power on transpose matrix.

In many cases, you will see that the superscripted T has been used before the matrix, and then the power has been used.

   \[ {^\mathsf{T}}\mathbf{A}^n,\;{^\mathsf{T}}\mathbf{A}^{-1}  \]
   \[ \left(\mathbf{A}^\mathsf{T}\right)^{-1} = \left(\mathbf{A}^{-1}\right)^\mathsf{T} \]
   \[ \left( \mathbf{AA}^\mathsf{T} \right)^\mathsf{T} = \left( \mathbf{A}^\mathsf{T}\right)^\mathsf{T}\mathbf{A}^\mathsf{T} \]

Output :

Use power of transpose.
