why it always apears “Address already in use: Cannot bind”？

x=udp('192.168.2.20',166, 'LocalPort', 5030);  
x.inputbuffersize=414720;
fopen(x);
fwrite(x,'get');
data=fread(x);
fclose(x);

Try quitting MATLAB and trying again: you might have an old connection sitting around from a previous attempt.

You may have an older connection still alive. Try quitting MATLAB and try again.

You can also turn 'EnablePortSharing' on to make a connection even if the port is already in use.

x.EnablePortSharing = 'on';
