How to store vector in column matrix?

So here is my for loop:

for i=1:1000
    x=randfixedsum(5,1,1,0,1);
    ret= x(1)*Returns(:,1) +x(2)*Returns(:,2) +x(3)*Returns(:,3) +x(4)*Returns(:,4) +x(5)*Returns(:,5);

      am=mean(ret)*251;
      as=std(ret)*sqrt(251);
  hold all
      plot(as,am,'r.')
  end

x is a 1x5 matrix that changes each loop, I am looking to store the values of each loop in a matrix so I know what values were used on each loop.

I tried adding in a

   y=[x(i);x(i+1)];

But that just gave an error. Any help would be great thanks

Outside for loop define

y = zeros(1000, 5);

and then inside for loop use

x=randfixedsum(5,1,1,0,1);
y(i, :) = x;

all the values will be stored in y.
