# CTAN Update: nicematrix

François Pantigny submitted an update to the
nicematrix
package.
Version: 5.11 2021-02-22
License: lppl1.3
Summary description: Improve the typesetting of mathematical matrices with PGF
Announcement text:

In the \CodeAfter and the code-before, instead of the syntax (row-i-|col-j) for the nodes which indicate the position of the (potential) rules, one should now use (i-|j). The syntax is simpler and the code has better legibility.

The package’s Catalogue entry can be viewed at https://ctan.org/pkg/nicematrix The package’s files themselves can be inspected at http://mirror.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.
