Summary description: Improve the typesetting of mathematical matrices with PGF
Announcement text:

New command \arraycolor in the \CodeBefore (with its key 'except-corners'). New key 'borders' for the command \Block. New command \Hline (for horizontal rules not drawn in the blocks). The keys 'vlines' and 'hlines' take in as value a (comma-separated) list of numbers (for the rules to draw). ---------------------------------------------------------------------- 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.
