How do you start a new column for every iteration in a loop?

I am loading trying to store each iteration in a separate column in: percent(j,:)=[percent_correct].

There should be a total of 11 columns with 50 rows. However, only the last 50 values are stored.

sid = 'data_x'; 

for ii = 1:11 

load([sid,num2str(ii),'.mat'])

for j = 1:50 

   num_words= numel(q.data.sent{j})
   num_correct=data(j,4)
   percent_correct=num_correct/num_words 
   percent(j,:)=[percent_correct] 

end

end

If data is a 2-dimensional array then percent_correct is a scalar so you need to make sure it is saved in one exact place in the percent array.

Also it helps if you preallocate the matrix before the loop:

rows = 50;
cols = 11;
percent = zeros(rows, cols);
for ii = 1:cols
  ...
  for j = 1:rows
    ...
    percent(j, ii)=[percent_correct];
  end
end
