# CTAN update: nicematrix

Date: July 16, 2020 8:38:58 PM CEST

François Pantigny submitted an update to the
nicematrix
package.
Version number: 5.0 2020-07-15
License type: lppl1.3
Summary description: Improve the typesetting of mathematical matrices with PGF
Announcement text:

In previous versions of nicematrix, it was mandatory, for technical reasons, to use the letters L, C and R instead of the letters l, c, r in the preambles of the environments of nicematrix. In this version 5.0, one must use l, c and r. For *compatibility* with previous versions, there is a key 'define-L-C-R' to use at load-time : \usepackage[define-L-C-R]{nicematrix} This version also provides a command \tabularnote to create tabular notes in {NiceTabular}. These tabular notes are composed at the bottom of the tabular. In this version, it's also possible to use \diagbox in a \Block.

This package is located at http://mirror.ctan.org/macros/latex/contrib/nicematrix More information is at http://www.ctan.org/pkg/nicematrix CTAN is run entirely by volunteers and supported by TeX user groups Please join a user group or donate to one, see https://ctan.org/lugs

Thanks for the upload. For the CTAN Team Ina Dau --

## 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;
- tabular notes;
- etc.

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