Please see this example in our documentation for the best way to communicate between two MATLAB sessions using UDP:

Nabeel Afridi, you can fwrite() the array in binary, or you can fprintf() the array. The code above shows a string being sent, and strings are arrays (of characters.) If the array is not fixed size you might be wanting to send the size information just before you send the array.

The UDP protocol does not guarantee transmission or order of the packets.
For most applications, you probably want to use TCPIP, like this:

Real-time communications require UDP rather than TCP, as TCP has no upper bound on packet delivery time and does not allow later packets to be delivered.
TCP is also not usable for broadcasting of any kind.
Effectively all other IP protocols other than TCP are unidirectional, so there are a lot of different applications where in-order guaranteed delivery is not suitable.
