Decide values of row in matrix for certain row intervals

Hi

I need to create a matrix where each row has the values of [1,0,0,0] over certain intervals as given below

rows=150001;window=500;
res=zeros(rows-window,4);
flagstart = [11600 42410 72480 102100 132000];  
flagend = [22620 52410 82550 112900 142200];
for ii = 1:numel(flagstart)
    res(flagstart(ii):flagend(ii),:) = [1,0,0,0];
end

This is the code i have got so far, but it is not working when i run it.

rows=150001;window=500;
res=zeros(rows-window,4);
flagstart = [11600 42410 72480 102100 132000];  
flagend = [22620 52410 82550 112900 142200];
for ii = 1:numel(flagstart)
    n = flagend(ii) - flagstart(ii)+1;
    res(flagstart(ii):flagend(ii),:) = repmat([1,0,0,0],n,1);
end

since you are just changing the first number, use res(a:b,1)=1
