for j=rr-3
    for i=1:rr-1
        if X(i)<=t(j) && t(j)<=X(i+1)
        N{1}(j,i)=1;
        else 
        N{1}(j,i)=0;
        end
    end
end

I want when the code catches N{1}(j,i)=1, then for the rest of N{1}(j,i)=0..How can I do this. I tried another ifelse and for lop but didn't work. Do you have any idea?

The program trying to catch N{1}(j,i)=1 and it does it properly.I want it to stop when N{1}(j,i)=0.

I am not so sure. But isn't there a break command for it?

break will exit the inner for-loop.

for j=rr-3
    for i=1:rr-1
        if X(i)<=t(j) && t(j)<=X(i+1)
           N{1}(j,i)=1;
        else 
           N{1}(j,i)=0;
           break;  % get out of the for-loop
        end
    end
end

To get out of both for-loops, you should add a flag

http://www.mathworks.com/matlabcentral/answers/40469-ask-about-break-function :

flag=0;
for ii=1:5
    ii
    if flag==1
       break
    end
    for jj=1:6
        jj
        if ii==3 && jj==4
            disp('broken here')
            flag=1;
            break;
          end
      end
  end
