kmunionclosure: Close a family of sets under union
Description
kmunionclosure returns a matrix representing a knowledge space. Please note
that it may take quite some time for computing larger knowledge spaces.
Usage
kmunionclosure(x)
Value
Binary matrix representing the corresponding knowledge space, i.e. the
closure of the family under union including the empty set and
the full set.
kmunionclosure implements the irredundant algorithm developed by Dowling (1993).
Arguments
x
Binary matrix representing a family of sets
