LaTeX Package: transposetikzmatrix

This package allows to transpose TikZ matrices using the xparse command \TransposeTikzMatrix #1.

The package is fully written in expl3 and xparse syntax.

Package Options

Using this package requires that you define the ampersand replacement property of your TikZ matrix. By default, this package assumes you have set ampersand replacement=\&. This requires you to use \& instead of & to separate entries within a matrix row.

You can choose to use a different control structure as ampersand replacement. For instance, if you prefer to use \x, you can provide the name of the control structure (without \) as the ampersand package option:

\usepackage[ampersand=x]{transposetikzmatrix}

Sample Use

This example can also be found in the sample-use.tex and sample-use.pdf files.
