@Misaki Soma - you are too impatient programmer. Please give more time to the user for typing an input :) It turns out that function for time less than 1s is not able to initialize correctly all objects.

It didn't work well in boucles, I don't know why it stops when I do:
valCont =NaN;
while (isnan (valCont))
valCont = waitinput(num2str(t),0.001,'s');
t = t+1;


thanks a lot. works perfect!!!

In line 37 should be:
error('The third argument to WAITINPUT must be ''s'', or ''d''.')

Instead of:
error('The second argument to WAITINPUT must be ''s'', or ''d''.')
