Snippet 1 - Matlab Arduino serial communication

.m

% XBee expects the end of commands to be delineated by a carriage return.
  xbee = serial(port,'baudrate',9600,'terminator','CR','tag','Quad');

  set(xbee, 'TimeOut', 5);  %I am willing to wait 1.5 secs for data to arive
  % I wanted to make my buffer only big enough to store one message
  set(xbee, 'InputBufferSize',  390 )
  % Before you can write to your serial port, you need to open it:
  fopen(xbee);
  
  disp('Serial port opened');
