How can I communicate between two instances of MATLAB on the same computer using UDP?

I'm trying to communicate between two instances of MATLAB opened on the same computer using UDP. I opened the second instance of MATLAB using the following code:

!matlab &

I am somewhat familiar with the "udp()" function, but I'm not sure how to declare the remote ports as these seem to change each time I open MATLAB.

Any assistance is greatly appreciated!

You can ask udp() to use particular local ports so have one of the instances use port 32109 as its local port and have the other use 32108 as its local port and have each specify the other value as the remote port.
