复杂网络的一些节点面对攻击的代码

function NodeIDs = GraphNodeIDs(Graph)
% Returns the list of node IDs in the graph
%
% Receives:
%       Graph      -   Graph Struct           -    the graph loaded with GraphLoad
%
% Returns:
%      NodeIDs    -     vector of integers    -    IDs of nodes, used in graph
% See Also:
