Command for Easily Representing Transpose Matrices in LaTeX
Code
Throughout mathematics, the notation for a transpose matrix is written as $A^{T}$, $A '$, and of course $A^{\mathsf{T}}$ as well. To indicate a transpose matrix most clearly, it is good to use $T$, but in practice $T$ can be confused with notation for time and the like, so a different font is used. Among these, the simplest command is \top, so that A^{\top} is rendered as $A^{\top}$.
| $\TeX$ | Rendering |
|---|---|
A^{T} | $A^{T}$ |
A \' | $A '$ |
A^{\mathsf{T}} | $A^{\mathsf{T}}$ |
A^{\top} | $A^{\top}$ |
Aside 1
In fact, \top was not made to be used for transpose matrices; it is said to have become \top in the sense that logic represents true/top. Conversely, false/bottom is \bot, which is actually rendered as $\bot$. However, since there is already \perp, $\perp$, a similar symbol that represents perpendicular, \top is not used in the same way.
