I have the following matrix:
which is obtained from the following code:

I was trying to change:
\begin{tikzpicture}[baseline={-0.5ex},mymatrixenv]
to
\begin{tikzpicture}[scale=2,baseline={-0.5ex},mymatrixenv]
but without effect.
I also tried this when I import the picture to another document:
\begin{figure}
\centering
\scalebox{2}{
\input{color_matrix3.tikz}
}
\end{figure}
the output was indeed bigger but not centered and latex gave a lot of errors concerning math equations
\usepackage{adjustbox} ... \adjustbox{scale=2,center}{...}or\begin{adjustbox}{scale=2,center}...\end{adjustbox}. Instead ofscale=2maybe awidth=\textwidthor some other length is more suitable. – Martin Scharrer Dec 28 '18 at 12:13
