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,:));
end
fclose(fid);

i don't have character array but a file

yourfile = 'filecompl.txt';
       
       size_file = size(yourfile);
       doc_name = [app.NomeFileEditField.Value, '.txt'];
       fid = fopen(fullfile(doc_name),'w');
        for i= 1:size_file(1)
            fprintf(fid, '%s\n',yourfile(i,:));
        end
       fclose(fid);
       

In this way i have a file containig the phrase 'filecompl.txt'

What i want is that filecompl.txt change in doc_name

I am confused here. Do you have a text file ready? and you want to read it and rename it using matlab editfields?

[Siria Fumagalli]

Exactly, except I don't want to read it, I only want to change the name using the edit field

[Ajay Kumar]

yourfile = 'filecompl.txt';
doc_name = [app.NomeFileEditField.Value, '.txt'];
movefile(yourfile,doc_name)
