# CTAN update: nicematrix

Following a discussion on TeX StackExchange (tex.stackexchange.com/questions/510841/nicematrix-and-tikz-external-optimize) this version allows the utilisation of 'nicematrix' with both 'standalone' and the optimization of Tikz externalization.

## nicematrix – Several features to improve the typesetting of mathematical matrices with TikZ

This package provides new environments similar to the environments
`matrix`, `pmatrix`, `bmatrix`, etc.
of amsmath and mathtools.

In these new environments, a TikZ node is created for each cell of the matrix.

The user can use these nodes directly but `nicematrix`
also provides commands which use these nodes to draw continuous
dotted lines from two cells of the matrix (the result is more
aesthetic than the classical result obtained using
`\cdots`, `\vdots`, `\ddots`, etc.).

This package also provides a control over the width of the columns and the possibility to add an exterior line and an exterior column.

`nicematrix` requires and loads
amsmath,
array,
expl3,
l3keys2e,
xparse,
tikz,
as well as the TikZ library `fit`.
