kmunionclosure: Close a family of sets under union

In kstMatrix: Basic Functions in Knowledge Space Theory Using Matrix Representation

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)

Arguments

x	Binary matrix representing a family of sets

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).
