clear display

I have a loop that takes about 10 minutes to run. As this takes longer than expected, I would like a simple note displayed on the workspace showing the percentage. I am successful doing:

for time=t'; %running time [hr]

    percent=round(time/size(t,1)*100);
    display(['Running... ',num2str(percent),'%'])

The problem is only that each loop displays the note, creating a long list on the workspace. How can I clear the displayed line at the end of the loop and replace it with the newer one to show a single line with a changing percent done?

Thanks!

clc clears the command window if that is what you want to do.

clc isn't quite it. I'd rather clear just the last line of the command window, not the entire thing. Any other ideas?

This code illustrates what I think you are after... but I am not sure it
will be quite what you want. If you don't have the pause in, you won't
see anything but the last statement because MATLAB tries to be efficient
about not writing to the command window "too often."

fprintf(1,'here''s my integer: ');
for i=1:9
fprintf(1,'\b%d',i); pause(.1)
end
fprintf('\n')

the function waitbar() may be a good choice for your need.

Both of those work well for me needs. Thanks!
