复杂网络的一些节点面对攻击的代码

function NodeNames = GraphGetNodeNames(Graph,NodeIDs)
% Returns the list of node Names, specified in the index of the graph
%
% Receives:
%       Graph      -   Graph Struct           -    the graph loaded with GraphLoad
%       NodeIDs    -   vector of integers     -    (optional) list of ids for which the names are required. Default: all nodes are returned.
%                                                   Values, not in the original index are empty cells.
% Returns:
%      NodeNames   -   cellstring             -    Names of the IDs in the order, identical to NodeIDs, If no IDs exist in the Graph, then empty cell is returen
