idealsFromGeneratingSets -- creates ideals from sets of monomials

Synopsis

Description

Given a list of sets of monomials, the function converts each set into a monomial ideal.

o6 : List
i7 : idealsFromGeneratingSets(B)

o7 = {monomialIdeal (x , x , x , x ), monomialIdeal (x , x , x , x ),
                      1   2   3   4                   1   2   3   4

                     1   2   3   4

o7 : List

In case the option IncludeZeroIdeals is set to false, the function also counts how many sets are converted to the zero ideal.
