# CTAN update: nicematrix

Date: June 24, 2019 8:10:23 PM CEST

François Pantigny submitted an update to the
nicematrix
package.
Version number: 2.2 2019-06-23
License type: lppl1.3
Summary description: Several features to improve the typesetting of
mathematical matrices with TikZ
Announcement text:

Possibility to draw horizontal dotted lines to separate rows with the command \hdottedline (similar to the classical command \hline and the command \hdashline of arydshln). Possibility to draw vertical dotted lines to separate columns with the specifier ":" in the preamble (similar to the classical specifier "|" and the specifier ":" of arydshln). It's possible to replace ":" by another letter with the option "letter-for-dotted-lines". This version is not strictly compatible with the previous ones since this new version will, be default, replace some vertical lines drawn by arydshln with lines drawn by nicematrix. However, an instruction \NiceMatrixOptions{letter-for-dotted-lines=V} will restore the previous behaviour.

## nicematrix – Improve the typesetting of mathematical matrices with PGF

This package is based on the package array. It creates PGF/TikZ nodes under the cells of the array and uses these nodes to provide functionalities to construct tabulars, arrays and matrices.

Among the features :

- continuous dotted lines for the mathematical matrices;
- exterior rows and columns (so-called border matrices);
- control of the width of the columns;
- tools to color rows and columns with a good PDF result;
- blocks of cells;
- etc.

The package requires and loads
l3keys2e,
xparse,
array,
amsmath,
pgfcore,
and the module `shapes` of
PGF.
