I have a code that generates a txt file by using the function writetable (shown below). In my code, I name the file 'final.txt'. However, I would like the user to be prompted to enter the name of the file while the code is running so that the file can be saved according to the users entered file name.

writetable(Results_Table,'final.txt','Delimiter','\t')

Use this code:

% Get the name of the file that the user wants to save.
startingFolder = userpath % Or "pwd" or 'C:\my results' or wherever you want.
defaultFileName = fullfile(startingFolder, '*.txt');
[baseFileName, folder] = uiputfile(defaultFileName, 'Specify a file');
if baseFileName == 0
	% User clicked the Cancel button.
	return;
end
fullFileName = fullfile(folder, baseFileName)
writetable(Results_Table, fullFileName, 'Delimiter', '\t')
