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.

Yes, the timer period will be _approximately_ 0.01 seconds.
I see Gerd has specified fixedRate, which is probably what you want. For more information on the choices, please see

What precision do you need on the 10 milliseconds?
Is there a USB / serial device involved in this, or is it a directly connected serial port?

Please note that if any USB device is installed, times of 10 millisecond will require special configuration or special programming.
