% Return the complement of a graph
|
||
|
|
% The complement graph has the same nodes, but edges where the original graph doesn't and vice versa.
|
||
|
|
%
|
||
|
|
% INPUTs: adj - original graph adjacency matrix, nxn
|
||
|
|
% OUTPUTs: complement graph adjacency matrix, nxn
|
||
|
|
%
|
||
|
|
% Note 1: Assumes no multiple edges.
|
||
|
|
% Note 2: To create a complement graph without self-loops,
|
||
|
|
% use adjC=ones(size(adj))-adj-eye(length(adj)); instead.
