# Confusion matrix in LaTeX

I used the proposed example in the "confusion matrix using only LaTeX code"

I increased the number of classes and until 9x9 confusion matrix, everything worked very well, but for 10 or higher numbers it got some errors. I upload the example with 10 columns:

\documentclass{article}
\usepackage{graphicx}

\newcommand\MyBox[1]{%
\fbox{\parbox[c][.7cm][c]{.7cm}{\centering #1}}%
}
\newcommand\MyVBox[1]{%
\parbox[c][.7cm][c]{1cm}{\centering\bfseries #1}%
}
\newcommand\MyHBox[2][\dimexpr.7cm+2\fboxsep\relax]{%
\parbox[c][1cm][c]{#1}{\centering\bfseries #2}%
}
\newcommand\MyTBox[10]{%
\MyVBox{#1}\MyBox{#2}\hspace*{-\fboxrule}\MyBox{#3}\hspace*{-\fboxrule}%
\MyBox{#4}\hspace*{-\fboxrule}%
\MyBox{#5}\hspace*{-\fboxrule}%
\MyBox{#6}\hspace*{-\fboxrule}%
\MyBox{#7}\hspace*{-\fboxrule}%
\MyBox{#8}\hspace*{-\fboxrule}%
\MyBox{#9}\hspace*{-\fboxrule}%
\MyBox{#10}\par\vspace{-\fboxrule}
}

\begin{document}

{
\offinterlineskip
\raisebox{-5cm}[0pt][0pt]{\rotatebox[origin=c]{90}{\parbox[c][0pt][c]{1cm}{\textbf{Source2}\\[20pt]}}}\par
\hspace*{1cm}\MyHBox[\dimexpr5.1cm+6\fboxsep\relax]{Source1}\par
\hspace*{1cm}\MyHBox{A}\MyHBox{B}\MyHBox{C}
\MyHBox{D}\MyHBox{E}\MyHBox{F}\par

\MyTBox{A}{1}{2}{3}{4}{5}{6}{7}{8}{9}
\MyTBox{B}{2}{3}{4}{5}{6}{7}{8}{9}{10}
\MyTBox{C}{3}{4}{5}{6}{7}{8}{9}{10}{11}
\MyTBox{D}{4}{5}{6}{7}{8}{9}{10}{11}{12}
\MyTBox{E}{5}{6}{7}{8}{9}{10}{11}{12}{13}
\MyTBox{F}{6}{7}{8}{9}{10}{11}{12}{13}{14}

• (1) welcome, (2) latex macros only support up to 9 args. Perhaps you should start by explaining what exactly you are trying to do (which is not really obvious from your code). – daleif Feb 13 '18 at 11:20
• try add \setcounter{MaxMatrixCols}{12} , see for example tex.stackexchange.com/questions/280520/rotate-matrix-in-latex/…. – Zarko Feb 13 '18 at 11:45

Rather than using 10 arguments for your macro you're better off using a comma separated list and then processing it using something like docsvlist from the etoolbox package. With this small modification your code produces:

Here's the full code:

\documentclass{article}
\usepackage{graphicx}

\newcommand\MyBox[1]{%
\fbox{\parbox[c][.7cm][c]{.7cm}{\centering #1}}%
}
\newcommand\MyVBox[1]{%
\parbox[c][.7cm][c]{1cm}{\centering\bfseries #1}%
}
\newcommand\MyHBox[2][\dimexpr.7cm+2\fboxsep\relax]{%
\parbox[c][1cm][c]{#1}{\centering\bfseries #2}%
}
\usepackage{etoolbox}
\newcommand\MyTBox[3]{%
\MyVBox{#1}
\renewcommand*\do[1]{\MyBox{##1}\hspace*{-\fboxrule}}
\docsvlist{#2}
\MyBox{#3}\par\vspace{-\fboxrule}
}

\begin{document}

{
\offinterlineskip
\raisebox{-5cm}[0pt][0pt]{\rotatebox[origin=c]{90}{\parbox[c][0pt][c]{1cm}{\textbf{Source2}\\[20pt]}}}\par
\hspace*{1cm}\MyHBox[\dimexpr5.1cm+6\fboxsep\relax]{Source1}\par
\hspace*{1cm}\MyHBox{A}\MyHBox{B}\MyHBox{C}
\MyHBox{D}\MyHBox{E}\MyHBox{F}\par

\MyTBox{A}{1, 2, 3, 4, 5, 6, 7, 8}{9}
\MyTBox{B}{2, 3, 4, 5, 6, 7, 8, 9}{10}
\MyTBox{C}{3, 4, 5, 6, 7, 8, 9, 10}{11}
\MyTBox{D}{4, 5, 6, 7, 8, 9, 10, 11}{12}
\MyTBox{E}{5, 6, 7, 8, 9, 10, 11, 12}{13}
\MyTBox{F}{6, 7, 8, 9, 10, 11, 12, 13}{14}
}

\end{document}


I made \MyTBox have three arguments as there is "special" processing for the header, body and footer respectively. This said, I'd probably do this differently using something like tikz, although this really depends on what you are really putting inside these macros:) -- but I like your macros too!

Thanks, I followed the comment from @daleif and managed to do it.

\newcommand\MyTBox[9]{%
%....
\MyTBoxcontinued
}
\newcommand\MyTBoxcontinued[2]{%
%two more arguments
}


In the following, I uploaded the code and the resulted image.
