复杂网络的一些节点面对攻击的代码

function Graph = GraphMakeUndirected(Graph)
% Reverses and duplicates each directional link in graph. If there exists a link A->B, then B->A is added. 
%
% Receives:
%   Graph       -   Graph Struct    -   the graph loaded with GraphLoad
%
% Returns:
%   Graph       -   Graph Struct    -   the graph loaded with GraphLoad without duplicate links
