复杂网络的一些节点面对攻击的代码

function Graph  = GraphConvertFromV2(Graph)
% Converts the Graph structure from V2 of the toolbox to V1. Links, weights, index and properties are converted. Up to 50% more space is requires.
%
% Receives:
%   Graph       -   Graph Struct                                -   the graph structure which can be used with any function of V2 of the toolbox.
%   
% Returns:
%   Graph       -   Graph Struct                                -   the graph structure compatible with the V1 of the Toolbox
