| Description | The Macek Project has been developed primarily for math researchers in matroid theory. This project is intended both to help with usual tiresome matroid routines, and to allow for long exhaustive computations over matroid classes. We suggest potential users to read the book [J.G. Oxley, Matroid Theory, Oxford University Press 1992]. The Macek package deals mainly with matroids represented by matrices over finite fields and partial fields. There are various tools for handling matroids, their matrices, and sets of matroids. One may pivot matrices, delete or contract matroid elements, and generate extensions for matroid representations. Structural tests for minors, equivalence, connectivity, branch-width, girth, etc, are also provided in the package. From 1.2, limited capabilities for computation with "abstract" matroid properties, like isomorphism, flats, aut group, and representability over other fields, are added. |
