# CTAN update: nicematrix

François Pantigny submitted an update to the
nicematrix
package.
Version: 5.15 2021-04-25
License: lppl1.3
Summary description: Improve the typesetting of mathematical matrices with PGF
Announcement text:

Key 'hvlines' for the command \Block. Now, the commands provided by nicematrix to color cells, rows and columns don't color the cells which are in the corners (specified by the key 'corners'). It's now possible to specify delimiters for submatrices in the preamble of an environment (inspired by the syntax of blkarray). Some bugs corrected.

The package’s Catalogue entry can be viewed at https://ctan.org/pkg/nicematrix The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/latex/contrib/nicematrix/

Thanks for the upload. For the CTAN Team Petra Rübe-Pugliese

## 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.
