Como posso forçar duas matrizes giradas a terem o mesmo tamanho, independentemente do conteúdo?

Question

Eu tenho duas matrizes que são giradas 45 graus uma ao lado da outra. Infelizmente, eles têm tamanhos diferentes, provavelmente porque um tem números de dois dígitos e o outro, um dígito.

Como posso forçá-los a ter o mesmo tamanho?

Aqui está meu MWE (graças a @marmot pelo código original):

\documentclass{article}
\usepackage{tikz}
\usepackage[utf8]{inputenc}
\usepackage{german}

\usetikzlibrary{matrix,shapes.geometric,positioning}

\begin{document}
\begin{figure}
\begin{tikzpicture}
 \matrix[matrix of nodes,transform canvas={rotate=45},
 nodes={regular polygon,regular polygon sides=4,draw,rotate=-45,shape border             rotate=45},
 row sep=-\pgflinewidth,column sep=-\pgflinewidth]
 (mat)
 {03 & 13 & 23 & 33 \\ 
 02 & 12 & 22 & 32 \\ 
 01 & 11 & 21 & 31 \\ 
 00 & 10 & 20 & 30 \\ 
 };
 \path ([xshift=-3mm,yshift=3mm]mat.south west |- mat.north west) rectangle 
 ([xshift=3mm,yshift=-3mm]mat.south east -| mat.north east);
 \node at (mat.south west) {$\Phi_1$};
 \node at (mat.south east) {$\Phi_2$};
\end{tikzpicture}
\qquad
\begin{tikzpicture}
 \matrix[matrix of nodes,transform canvas={rotate=45},
 nodes={regular polygon,regular polygon sides=4,draw,rotate=-45,shape border     rotate=45},
 row sep=-\pgflinewidth,column sep=-\pgflinewidth]
 (mat)
 {1 & 3 & 5 & 6 \\ 
 1 & 3 & 4 & 5 \\ 
 1 & 2 & 3 & 3 \\ 
 0 & 1 & 1 & 1 \\ 
 };
 \path ([xshift=-3mm,yshift=3mm]mat.south west |- mat.north west) rectangle 
 ([xshift=3mm,yshift=-3mm]mat.south east -| mat.north east);
 \node at (mat.south west) {$\Phi_1$};
 \node at (mat.south east) {$\Phi_2$};
\end{tikzpicture}

Answer 1

Basta adicionar a minimum sizechave para ambos os estilos de nó nas duas matrizes:

\documentclass{standalone}
\usepackage{tikz}
\usepackage[utf8]{inputenc}
\usepackage{german}

\usetikzlibrary{matrix,shapes.geometric,positioning}

\begin{document}
\begin{tikzpicture}
 \matrix[matrix of nodes,transform canvas={rotate=45},
 nodes={minimum size=1.3cm,regular polygon,regular polygon sides=4,draw,rotate=-45,shape border             rotate=45},
 row sep=-\pgflinewidth,column sep=-\pgflinewidth]
 (mat)
 {03 & 13 & 23 & 33 \\ 
 02 & 12 & 22 & 32 \\ 
 01 & 11 & 21 & 31 \\ 
 00 & 10 & 20 & 30 \\ 
 };
 \path ([xshift=-3mm,yshift=3mm]mat.south west |- mat.north west) rectangle 
 ([xshift=3mm,yshift=-3mm]mat.south east -| mat.north east);
 \node at (mat.south west) {$\Phi_1$};
 \node at (mat.south east) {$\Phi_2$};
\end{tikzpicture}
\qquad
\begin{tikzpicture}
 \matrix[matrix of nodes,transform canvas={rotate=45},
 nodes={minimum size=1.3cm,regular polygon,regular polygon sides=4,draw,rotate=-45,shape border     rotate=45},
 row sep=-\pgflinewidth,column sep=-\pgflinewidth]
 (mat)
 {1 & 3 & 5 & 6 \\ 
 1 & 3 & 4 & 5 \\ 
 1 & 2 & 3 & 3 \\ 
 0 & 1 & 1 & 1 \\ 
 };
 \path ([xshift=-3mm,yshift=3mm]mat.south west |- mat.north west) rectangle 
 ([xshift=3mm,yshift=-3mm]mat.south east -| mat.north east);
 \node at (mat.south west) {$\Phi_1$};
 \node at (mat.south east) {$\Phi_2$};
\end{tikzpicture}
\end{document}

Outra solução (melhor) graças a@marmota: Adicionaremos text width={width(33)}e align=centerà segunda matriz. Agora as duas matrizes têm o mesmo tamanho:

\documentclass[margin=5mm]{standalone}
\usepackage{tikz}
\usepackage[utf8]{inputenc}
\usepackage{german}

\usetikzlibrary{matrix,shapes.geometric,positioning}

\begin{document}
\begin{tikzpicture}
 \matrix[matrix of nodes,transform canvas={rotate=45},
 nodes={regular polygon,regular polygon sides=4,draw,rotate=-45,shape border             rotate=45},
 row sep=-\pgflinewidth,column sep=-\pgflinewidth]
 (mat)
 {03 & 13 & 23 & 33 \\ 
 02 & 12 & 22 & 32 \\ 
 01 & 11 & 21 & 31 \\ 
 00 & 10 & 20 & 30 \\ 
 };
 \path ([xshift=-3mm,yshift=3mm]mat.south west |- mat.north west) rectangle 
 ([xshift=3mm,yshift=-3mm]mat.south east -| mat.north east);
 \node at (mat.south west) {$\Phi_1$};
 \node at (mat.south east) {$\Phi_2$};
\end{tikzpicture}
\qquad
\begin{tikzpicture}
 \matrix[matrix of nodes,transform canvas={rotate=45},
 nodes={text width={width(33)},regular polygon,regular polygon sides=4,draw,rotate=-45,shape border     rotate=45,align=center},
 row sep=-\pgflinewidth,column sep=-\pgflinewidth]
 (mat)
 {1 & 3 & 5 & 6 \\ 
 1 & 3 & 4 & 5 \\ 
 1 & 2 & 3 & 3 \\ 
 0 & 1 & 1 & 1 \\ 
 };
 \path ([xshift=-3mm,yshift=3mm]mat.south west |- mat.north west) rectangle 
 ([xshift=3mm,yshift=-3mm]mat.south east -| mat.north east);
 \node at (mat.south west) {$\Phi_1$};
 \node at (mat.south east) {$\Phi_2$};
\end{tikzpicture}
\end{document}
