Hi Paskah,
you can use timers in Matlab to send continously data to your serial device.
t = timer ;
set(t,'ExecutionMode','fixedRate');
set(t,'Period',0.01);
set(t,'TimerFcn',{@mytimer_serial, handles});
start(t)
In the mytimer_serial function you can fire the command to the serial line. But please be careful about the precision as Walter already stated.
