Thread Subject:

flow,ceil, sortrows

hi,
i need someone to explain me these following matlab code
thanks.
function [NodeFlowMetric,MinHopMetric]=FlowCreate(NodeInfo,InterFlowNo,ExterFlowNo)
global NodeAmount; %????
global TransDistance; %???????


NodeFlowMetric=zeros(NodeAmount,(InterFlowNo+ExterFlowNo));
MinHopMetric=zeros(1,(InterFlowNo+ExterFlowNo));
NodeInfo=sortrows(NodeInfo,-4);
for i=1:InterFlowNo
    Source=ceil(NodeAmount*rand);
    while Source<3
          Source=ceil(NodeAmount*rand);
    end
    Destination=ceil(NodeAmount*rand);
    while Destination<3 || Destination==Source
          Destination=ceil(NodeAmount*rand);
    end
    SourceNode=NodeInfo(Source,1);
    DestinationNode=NodeInfo(Destination,1);
    NodeFlowMetric(SourceNode,i)=-1;
    NodeFlowMetric(DestinationNode,i)=1;
    SDDistance=((NodeInfo(Source,2)-NodeInfo(Destination,2))^2+(NodeInfo(Source,3)-NodeInfo(Destination,3))^2)^0.5;
    MinHop=ceil(SDDistance/TransDistance)+1;
    MinHopMetric(1,i)=MinHop;
end

You should ask the author of the code.
