dual: Dual hypergraph.

Description

Construct the dual hypergraph of a hypergraph.

Usage

dual_hypergraph(h)

Arguments

h

a hypergraph.

Value

a hypergraph.

Details

The dual hypergraph is a hypergraph whose nodes are the original hyper-edges, with hyper-edges indicating the original incidence. Essentially, the incidence matrix of the dual hypergraph is the transpose of the original incidence matrix.
