Increase lengthof variable in a for loop by a certain increment.

hello I have a for loop and wish to increase the length of my start variable by an increment value that i can later choose. It is basically crea ting the attenuation of a pulse train without using the pulstran function. this is how far I have got, but I either have to preallocate a variable which I've done or I'm iout of memory.

      Nclick=10 %number of clicks;
      start=((1:Nclick)*60e-3)/(1/fs); % defines a vector of start positions
      y3=zeros(1,length(twin));
      for ii=1:length(start);
        length(start)= length(start)*0.5;
          y3(start3(ii):start3(ii)+length(y2)-1)=y2;
      end;

Don't use length as a variable:

length(start)= length(start)*0.5;

You're creating length as a variable which obfuscates the function.
