# nicematrix – Improve the typesetting of mathematical matrices with PGF

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

In these new environments, a PGF 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,
pgf,
as well as the TikZ library `fit`.
