NonminimalComplexes :: NonminimalComplexes

NonminimalComplexes -- support for computing homology, ranks and SVD complexes, from a chain complex over the real numbers

Description

Some functionality here should be moved elsewhere.

Caveat

Currently, this package requires that the Macaulay2 being run is from the res-2107 git branch
