Code overwrites results in for loop. Cannot figure out how to index.

I've run into a problem with the following code, which is part of a for loop with index k.
if strcmp(l(1:5),'alpha') %Get row starting with alpha
l = fgetl(fid); % get next line
first_data = str2num(l);
alpha_beta = [first_data(1) first_data(3)]; % store alpha and beta
end
My issue is that the alpha_beta variable keeps overwriting with each iteration of the for loop. Ideally I'd like to save first_data(1) and first_data(3) from each iteration in alpha_beta. I tried a few things with indexing including
alpha_beta{k} = [first_data(1) first_data(3)];
but because it's a 'double' it won't allow brace indexing. I can't seem to find any alternatives, so if anyone has a suggestion it would be much appreciated.

Either
alpha_beta(k,1) = first_data(1);
alpha_beta(k,2) = first_data(3);
or
alpha_beta(k,1:2) = first_data([1,3]);
And remeber to preallocate alpha_beta before the loop:
