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.

Ran in:
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'}
