You can do this. Suppose you entered 'oldname' in text editfield. i.e.
your_editfield.Value = 'oldname';
now save the file using the name
yourfile = % your character array
size_file = size(yourfile);
doc_name = [your_editfield.Value, '.txt'];
fid = fopen(fullfile(yourpath,doc_name),'w');
for i= 1:size_file(1)
fprintf(fid, '%s\n',yourfile(i,:));
