UDP packets are used to send data from one computer to another over a network or from one application to another within a single computer.
The judp.m program uses Matlab's ability to call Java code to enable it to send and/or receive UDP packets. One Matlab session can communicate with another Matlab session (on the same machine or over the network) or it can communicate with a completely different program (again, on the same machine or over the network).
