I have the matrix:

which is obtained from the following code:

usetikzlibrary{patterns}

usetikzlibrary{matrix,decorations.pathreplacing,calc}

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 tryied 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
