package.
Version number: 5.6 2020-11-08 License type: lppl1.3
Summary description: Improve the typesetting of mathematical matrices with PGF
Announcement text: ----------------------------------------------------------------------
The height and the depth of the mono-row blocks (created with Block) are taken into account for the depth and the height of the current row.
New command NotEmpty to specify explicitely that a cell must be considered as non-empty (and so, a PGF/Tikz node is created in the cell).
