# CTAN update: nicematrix

Date: May 28, 2020 5:48:49 PM CEST

François Pantigny submitted an update to the
nicematrix
package.
Version number: 4.1 2020-05-27
License type: lppl1.3
Summary description: Improve the typesetting of mathematical matrices
with PGF
Announcement text:

New options 'cell-space-top-limit' and 'cell-space-bottom-limit' (inspired by the package 'cellspace'). New command '\diagbox' The key 'hvlines' now draws all the vertical and horizontal rules *excepted* in the blocks (created by '\Block') and in the virtual blocks corresponding to the dotted lines (drawn by '\Cdots', '\Vdots', etc.) Creation of PGF/Tikz nodes corresponding to the position of the rules, called 'row-1', 'row-2', etc. and 'col-1', 'col-2', etc. These nodes are accessible in the 'code-before' and in the 'code-after'.

This package is located at http://mirror.ctan.org/macros/latex/contrib/nicematrix More information is at https://www.ctan.org/pkg/nicematrix

## 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.
