Im doing a project on directed networks. I have a 2000x2 array in total created by a loop, running 9 times (once per week.) I need for every week to have no dublicated rows, but dublicated rows are allowed in the array for all weeks. I dont doubt the answer is simple, but i cant come up with new answers right now.

the loop is like this

for k=1:9
    for i=1:length(NumeriskData)
       if NumeriskData(i,DateRow)>= Ar(k,1) && NumeriskData(i,DateRow)<= Ar(k,2)
            if NumeriskData(i,RowSorter)== 1 || NumeriskData(i,RowSorter2)== 1 || NumeriskData(i,RowSorter3)== 1
               if NumeriskData(i,1)~= NumeriskData(i,2) 
                    WeightLink(Count+1,:)=  NumeriskData(i,1:2) ;
                    Count=Count+1;
                end
            end    
       end
    end
end

Unique(WeightLink) after here would just take uniques of the total array, i need it to take of every k run, and still make the proper total WeightLink

EDIT. Sorry, not sure how to format the code properly.

Hey Kian,

I am not sure if I really understood your problem, but maybe the following solution helps:

%Assuming NumeriskData is a nx2 matrix.
for k=1:9
  IsData = NumeriskData(:,DateRow)>= Ar(k,1) ...
         & NumeriskData(:,DateRow)<= Ar(k,2) ...
         & NumeriskData(:,1)~= NumeriskData(:,2) ...
         & (NumeriskData(:,RowSorter )== 1 ...
          | NumeriskData(:,RowSorter2)== 1 ...
          | NumeriskData(:,RowSorter3)== 1);
  if any(IsData)
    NumDatWeek = unique(NumeriskData(IsData,:),'rows');
    nNumDataWeek = size(NumDatWeek,1);
    WeightLink(Count+1:Count+nNumDataWeek,:) = NumDatWeek;
    Count = Count+nNumDataWeek;
  end
end
