adding answers into cell array

so i have a loop function that everytime it runs generates an output. example:

res = 'random words'

next time it runs...

res = 'another answer'

again...

res = 'another answer'

etc...so everytime it runs and generates an answer (some may be the same), I would like to record it. The end goal being that it lists all the outputs (without repeating any!) in a cell array format.

like so:

{'random words'} {'another answer'}

any sugguestions for how to go about getting these results all into an cell array? currently it just gives me an output of whatever the last result was and i want to have all the results.

One way:

answers = {};
for n = 1 : 10
    % My very complex computation
    res = sprintf('The answer is %i', randi(5));
    answers{end+1} = res;
end
answers % showing answers with duplicates for reference

answers = 1×10 cell array
    {'The answer is 2'}    {'The answer is 1'}    {'The answer is 3'}    {'The answer is 2'}    {'The answer is 5'}    {'The answer is 5'}    {'The answer is 5'}    {'The answer is 3'}    {'The answer is 3'}    {'The answer is 5'}

answers = unique(answers,'stable') % final result

answers = 1×4 cell array
    {'The answer is 2'}    {'The answer is 1'}    {'The answer is 3'}    {'The answer is 5'}

Another way:

answers = {};
for n = 1 : 10
    % My very complex computation
    res = sprintf('The answer is %i', randi(5));
    if ~ismember(res,answers)
        answers{end+1} = res;
    end
end
answers

answers = 1×5 cell array
    {'The answer is 4'}    {'The answer is 1'}    {'The answer is 5'}    {'The answer is 3'}    {'The answer is 2'}

Hi. You could do like this:

answers = {};
for n = 1 : 10
    % My very complex computation
    res = sprintf('The answer is %i', n);
    answers{end+1} = res;
end
answers

answers = 1×10 cell array
    {'The answer is 1'}    {'The answer is 2'}    {'The answer is 3'}    {'The answer is 4'}    {'The answer is 5'}    {'The answer is 6'}    {'The answer is 7'}    {'The answer is 8'}    {'The answer is 9'}    {'The answer is 10'}
