Saving data from loops

Sir I have the following code. I have to store all the value of choice for (1 to n) iterations. How can I do it?

for index = 1 : length(accumulation)
    if (accumulation(index) > p)
      chosen_index = index;
      break;
    end
  end  
  choice = chosen_index;

What values are you going to store? The chosen_index is for sure a scalar because as soon as the condition is satisfied once the loop stops executing, your code is achieved using one line:

 The_chosen_one = find(accumulation > p,1,'first')

If your question is how to store values in a loop then:

% an example
 x = randi(10,1,10);
 y = zeros(size(x)); % preallocate
 for k = 1:numel(x)
     y(k) = x(k) * 2;
 end

There are two ways to do it.

x = [];
for i = 1:n
    x = [x; choice(i)]
end

Above code will append the value of choice at ith index to the x.

x = zeros(n,1);
for i = 1:n
    x(i) = choice(i);
end

You can also preallocate and assign the value to ith index of x.
