I am trying to extract all the values from a for loop

I am trying to extract all the values from my for loop. the total data is 3 that satiesfies my condition inside the loop but, when i see on the workspace, it has only one variable after the loop.

Here is the code:

time=[];
for ii=2:size(time)-1
    if dt(ii)>=30 && Vol(ii)>23.5 && Volt(ii)>=23
      disp(times(ii));
    time=n_time(ii);
    end
 end
   time(1,:)=time;

When i see the displayed results it has 3 times, but, when i check the value inside the time vector it has only one value. Can you help me to extract all the 3 values which i getting, the one which satisfies the condition.

You could use a counter:

k = 0: % initialize outside loop
    :
    k = k + 1;
    time(k) = n_time(ii);

That being said, if you initilize time=[] as an empty variable, how do you expect your loop to do anything if the upper index bound uses size(time)? Maybe you meant numel(times) here instead. Or maybe a vectorized approach without a loop would be better:

    time = times(dt>=30 & Vol>23.5 & Volt>=23);

Actually after it satisfies the condition it should get the values from n_time, n_time is an array of timestamps

time=n_time(ii);

So all the values that satisfies the condition are 3 values. That's why i need those values stored in an array called time.
