I have following code

input = [1,0,1,0,0,1,1,1,1,1,0,1,0,1,0,1,0,1,1,1,1,1,1,0,1,0,1,0,1,1,1,1,1,1,0];
[m,n] = size(input);
i = 1;
startSig = [1,0,1];
allSwitch = zeros(3,n);
while i <= n-2
      if isequal(input(1,i:i+2),startSig)
          outputSwitch = bi2de(input(1,i+4:i+5));
          j=i+6;
         % cond = 0;
          k = 1;
          output = zeros(1,n);
          while j <= n && input(j) ~= 0 
              output(j) = input(1,j);
              k = k+1;
              j = j+1;
          end
          allSwitch(outputSwitch,:)=output;
          i = j+1;
      else
          i = i+1;
      end
  end
  Switch1 = allSwitch(1,:)
  Switch2 = allSwitch(2,:)
  Switch3 = allSwitch(3,:)

But when I use this code deleting the input values in simulink matlab use defined function block I did not get any out. I use here same input sequence used in matlab as square pulse.
