How to save the variables inside for loop

I am executing loop for k=1,2,5,6,.......100 E=produces column vector of different size; end

I need to save 'E' for each value of k;

Thanks Any help is appreciated!

The easiest way to probably to just use a cell array.

 Es = cell(100,1)

 for i = 1:100 %your loop

   % do stuff; generate E
   Es{i} = E

 end

I'm assuming you already have the loop working, you're just trying to save the output. This will be stored in Es.

Thank you very much! Could we do something in vector without cell operation? Thanks

It would probably be difficult; all your vectors are of different sizes, which means you can't just stack them into a big matrix. If you knew they had a max size M then you could do this:

 Es = NaN(100,M);

 for i = 1:100 %your loop
  %do stuff, generate E
  Es(1:length(E)) = E;
 end

This will store E in the first elements of Es for each row; the rest will be NaN values. The problem is that this is pretty inefficient in terms of memory, but it might work. You also need to know M which is difficult.
