how to save for loop variable output data in csv file?

I want to save for loop output in csv file. I want to save value of "label_index_expected" in csv file.I have tried but i am not getting how to save it.

for i = 1 : size(TV.T, 2)
      [x, label_index_expected]=max(TV.T(:,i));
      [x, label_index_actual]=max(TY(:,i));
      if label_index_actual~=label_index_expected
          MissClassificationRate_Testing=MissClassificationRate_Testing+1;
      end

numcol = size(TV.T, 2);
expecteds = zeros(numcol, 1);
for i = 1 : 
    [x, label_index_expected]=max(TV.T(:,i));
    expecteds(i) = label_index_expected;
    [x, label_index_actual]=max(TY(:,i));
    if label_index_actual~=label_index_expected
        MissClassificationRate_Testing=MissClassificationRate_Testing+1;
    end
end

csvwrite('Youroutput.csv', expecteds);

It is possible to write each one out as you go, but it is not usually efficient to do so.
