# CTAN update: nicematrix

Date: February 29, 2020 9:23:59 PM CET

François Pantigny submitted an update to the
nicematrix
package.
Version number: 3.12 2020-02-28
License type: lppl1.3
Summary description: Improve the typesetting of mathematical matrices with TikZ
Announcement text:

New command \rotate to rotate by 90° the cells of the array. Option 'vlines' to draw automatically all the vertical rules (similar to hlines). Option 'baseline' for {NiceArray}: the baseline of the whole array can be set equal to the baseline of a row of the array (given by its number). The name of the Tikz nodes created by the command \Block has changed: when the command has been issued in the cell i-j, the name of the node corresponding to that block is now 'i-j-block'. A 'medium' node may also be created for that 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

## 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.
