Graphics, Figures & Tables ⇒ NiceMatrix: Error when using large matrices with Block-Command

[Tetrahedron]

First of all, hey guys and thanks

The problem occurs when using the NiceMatrix-Package with the \Block-Command. It seems like there is a problem, if the matrix-indicies that the block covers exceed 10.

First of all, a working example:

Code: Select all

\documentclass[12pt]{article}

\usepackage{amsmath}
\setcounter{MaxMatrixCols}{15}

\usepackage[latin1]{inputenc}

\usepackage{nicematrix}

\begin{document}

\begin{equation}
\begin{bNiceArray}{CCC|CCC|CCCCC}[first-row,first-col]
	  & a & b & c & d & e & f & g & h & i & j & k \\
	a & \Block{3-3}{A} & & & \Block{3-3}{B} & & & \Block{3-3}{C} & & & & \\ % does compile
	b & & & & & & & & & & & \\
	c & & & & & & & & & & & \\
	d & \Block{3-3}{D} & & & \Block{3-3}{E} & & & 0 & 0 & 0 & 0 & 0 \\ 
	e & & & & & & & 0 & 0 & 0 & 0 & 0 \\
	f & & & & & & & 1 & 0 & 0 & 0 & 0 \\
	g & 0 & 0 & 0 & \Block{3-3}{F} & & & 0 & 1 & 0 & 0 & 0 \\
	h & 0 & 0 & 0 & & & & 0 & 0 & 1 & 0 & 0 \\
	i & 0 & 0 & 0 & & & & 0 & 0 & 0 & 1 & 0 \\
	j & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 1 
\end{bNiceArray}
\end{equation}

\end{document}

Not working:

Code: Select all

\documentclass[12pt]{article}

\usepackage{amsmath}
\setcounter{MaxMatrixCols}{15}

\usepackage[latin1]{inputenc}

\usepackage{nicematrix}

\begin{document}

\begin{equation}
\begin{bNiceArray}{CCC|CCC|CCCCC}[first-row,first-col]
	  & a & b & c & d & e & f & g & h & i & j & k \\
	a & \Block{3-3}{A} & & & \Block{3-3}{B} & & & \Block{3-5}{C} & & & & \\ % does not compile
	b & & & & & & & & & & & \\
	c & & & & & & & & & & & \\
	d & \Block{3-3}{D} & & & \Block{3-3}{E} & & & 0 & 0 & 0 & 0 & 0 \\ 
	e & & & & & & & 0 & 0 & 0 & 0 & 0 \\
	f & & & & & & & 1 & 0 & 0 & 0 & 0 \\
	g & 0 & 0 & 0 & \Block{3-3}{F} & & & 0 & 1 & 0 & 0 & 0 \\
	h & 0 & 0 & 0 & & & & 0 & 0 & 1 & 0 & 0 \\
	i & 0 & 0 & 0 & & & & 0 & 0 & 0 & 1 & 0 \\
	j & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 1 
\end{bNiceArray}
\end{equation}

\end{document}

Of course, the matrix C should be the size 3-5 instead of 3-3 to cover the empty space inside the matrix. But after replacing "\Block{3-3}{C}" with "\Block{3-5}{C}" (that is the only difference between the two examples), I get the following error message:

Code: Select all

Package pgf Error: No shape named `nm-1-col-21' is known. \end{bNiceArray}

I would be really happy, if there's a work-around or similar for that.

Thanks in advance!

It is working as expected.

First I tried your working example. CHanged 3 to 5; it worked. Copied your "non-working" code. That also compiled without any errors.

Thanks for your replay.

The problem occurs with version 3.13 of NiceMatrix.

It seems, like there are no problems with 3.11 and older... which version did you use?

This is a bug in NiceMatrix 3.13

The author will fix it in the update 3.14
