# pmatrix and superscript

I would like to place a superscript to a pmatrix, but the superscript is not correctly positioned.

\begin{pmatrix}
1 & 2 & 3 \\
4 & 5 & 6 \\
7 & 8 & 9
\end{pmatrix}^{T}


Any suggestions?

• looks OK to me but you can shift it to the left with some negative space {\!\!T} May 15 '13 at 7:50

One of the reasons why I always use (square) brackets for delimiting matrices is that the larger the matrices are, the fatter the parentheses become.

Compare the two results, one with pmatrix, the other with bmatrix:

The parentheses don't add to clarity, only to the required space.

One might argue that the "T" is too far also in the second case, but I don't think so. The following shows the result with

^{\!\!T}


after the pmatrix and

^{\!T}


after the bmatrix (which I believe is overkerning):

A problem with pmatrix is that the backup depends on the size of the matrix: \!\! would probably be too much for a 2-by-2 matrix.
