Several features to improve the typesetting of mathematical matrices with TikZ
Description
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;
etc. The package requires and loads l3keys2e, xparse, array,
amsmath, pgfcore, and the module shapes of PGF.
