Generating a text file and autofill it with outputs

Hello! Is there a way to generate a .txt file and fill it with strings, one on each row, in a for loop? To be exact, in a for loop i generate different outputs and i want to save all of them in a .txt file but i don't know how.

for i=1:length(text)

linie=find(key(i)==alfabet);

coloana=find(text(i)==mat(linie,:));

decrypt=[decrypt mat(1,coloana)];

end

decrypt

Yes!

fid = fopen('output_file.txt','wt'); % Open output_file.txt
% 'w' means overwrite everything that is already in the file, use 'a' to
% append instead. 't' means format more like a text file

for i=1:length(text)
    linie=find(key(i)==alfabet);
    coloana=find(text(i)==mat(linie,:));
    decrypt=[decrypt mat(1,coloana)];
    fprintf(fid,'%s\n',coloana); % To the file already opened (identified by fid)
    % write a single line (%s) followed by a newline symbol (\n)
    % '%s' tells the function to expect a string input; if the input
    % you want to write to the file is not a string you'll need to change
    % the formatting identifier. A link to the function is below.
    
end
decrypt

fclose(fid) % close the opened file

Functions: fopen, fprintf (direct link to formatting inputs), fclose
