Answer 1

You seem to have an somewhat inconvenient character array. You can convert this array in a more manageable form by doing something like what @Richante said:

strings = strread(a, '%s', 'delimiter', sprintf('\n'));

Then you can reference to toto and titi by

>> b = strings{2}
b = 
toto

>> c = strings{3}
c = 
titi

Note that strings{1} is empty, since a starts with a newline character. Note also that you don't need a strtrim -- that is taken care of by strread already. You can circumvent the initial newlines by doing

strings = strread(a(2:end), '%s', 'delimiter', sprintf('\n'));

but I'd only do that if the first newline is consistently there for all cases. I'd much rather do

strings = strread(a, '%s', 'delimiter', sprintf('\n'));
strings = strings(~cellfun('isempty', strings))

Finally, if you'd rather use textscan instead of strread, you need to do 1 extra step:

strings = textscan(a, '%s', 'delimiter', sprintf('\n'));
strings = [strings{1}(2:end)];
