The question is not clear yet. Please post what you have tried so far and ask a specific question.

I have an experiment and I need to stimulat the subject (ask the subject to make task (hand tapping) 10 second and stop tapping (rest) 20 second ) spontenuosly and repeat this stimulas 20 times ( 20 second + 10 second ) X 20 and show the task on screen " Hand tapping " / " Rest " within this task I need to record the brain signal

So it is sometimes tapping for 10 seconds and sometimes for 20 seconds?

For these kinds of work I recommend using Psychtoolbox http://psychtoolbox.org/ as it is designed specifically for presenting stimuli for precise times.

Answer 2

[Jan]

pause(60);
for k = 1:20
    disp('Tap');
    pause(10)
    disp('Rest');
    pause(20);
end

The sleep command of java has a smaller jitter than the pause command:

% replace pause(duration) by:
java.lang.Thread.sleep(duration * 1000);

thanks @Jan exactly what I want to do but "Tap" / ''Rest " in full schreen, is it possible ?

[Jan]

What exactly does "Tap in full screen" mean? "Full screen" can mean a Matlab figure with visible borders and menu bar, or without the borders, with or without the taskbar of the operating system.
