How to display text in the same line after processing?

When I begin some data processing, I display a message - something like "Processing xyz file", after finishing the processing, I would like to display done but have it printed in the same line as before, such that it would look something like "Processing xyz file ..... done". How can i display "done" in the same line ?

Thank you !

Try the following (not on line)

s1 = 'Processing xyz123 file';
fprintf('%s', s1);   % printing without change line

Processing xyz123 file

pause(1)  % processing

% go back the beginning of the line
for i=1:length(s1)
    fprintf('%c', char(8));  % backspace one char
end

fprintf('Finished. \n')

Finished.

Somthing like this?

fprintf('Processing xyz file .....');
a = rand(10000,10000);
fprintf('done')
