Matroid
The flats of a matroid are those subsets which are maximal with respect to their rank. Given a matroid, the Flats command returns the flats of that matroid as a list of sets.
If the flats of this matroid haven't been computed before, they are computed by this command and stored for any future computations that use the flats.
Find the sets of indices whose corresponding columns form a flat in the column space of a matrix.
