Hi. I'd like to know if is it possible to modify a string (or part of it) from outside, i.e. create a new ".m" file and modify, or change, strings of an existent ".m" file from the new one. Thanking you for your attention, I'm looking forward for your answers.

Hi Antonio,
Your question is a bit unclear. Are you saying that you want to do a search/replace in the m-file, and then write out the replaced file as a new file? If so, you can either use the "Find & Replace" utility in the Matlab IDE (Ctrl+F), or you can do it in code using something like this:
str = fileread('/path/to/your/mfile.m');
newstr = strrep(str, 'oldtext1', 'replacetext1');
newstr = strrep(newstr, 'oldtext2', 'replacetext2');
% etc.
%now write new file
fid = fopen('/path/to/newfile.m', 'wt');
fprintf(fid, '%s', newstr);
fclose(fid);
