¿Cómo puedo forzar que dos matrices rotadas tengan el mismo tamaño independientemente del contenido?

Question

Tengo dos matrices que giran 45 grados una al lado de la otra. Desafortunadamente, son de diferentes tamaños, probablemente porque uno tiene números de dos dígitos y el otro de un dígito.

¿Cómo puedo obligarlos a que sean del mismo tamaño?

Aquí está mi MWE (gracias a @marmot por el 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}

Solo es necesario agregar la minimum sizeclave para ambos estilos de nodo en las dos matrices:

\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}

Otra solución (mejor) gracias a@marmota: Sumaremos text width={width(33)}y align=centera la segunda matriz. Ahora las dos matrices tienen el mismo tamaño:

\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}
