Saving/Visualizing all loop results

Good morning,

I think my question must be quite simple but I don't find how to resolve it. I have a loop and I want to 'save' (or at least visualize) the results. The problem is with the code I only can 'save/see' the 'last' column, not all (not all the results of the iteration). Here's the code:

b = xlsread('Data.xls', 'Sheet1'); %here I'm reading the excel data
d= size(b); % the size of the input table is 8 x 16 columns.
cols= d(:,2); 
Results=[]

for a=b(:,2:cols)

       n= 2;
       m2 = ar(a,n);
      K=6;
      hf2=forecast(m2,a,K); 

   for a=b(:,2:cols) % here I try to save the results but it only save the 'last column', not all the columns. 
       Results=[forecast(m2,a,K)]
    end
  end

What could be the problem?

Thanks in advance! :)

I assume you intentionally have two for loops, correct?

Either way, in case you do not know the size of the final matrix you can simply append vectors:

 Results = [Results forecast(m2,a,K)]

Thanks Mischa! I had a problem because I was repiting the iteration but now is solved! thanks a lot! :)
