Sorry, I do not use Simulink.

There is a toolbox that has TCP and UDP, but you can also use the
tcpudpip Matlab File Exchange contribution.

I haven't use Matlab for TCP or UDP myself; my background happens to
include networking work so I know the theory but not so much of how
Matlab implements it.

Hey,
So there are two ways you can send data to remote machine. Like Walter said, using command line or there are Simulink blocks that can be used. In Simulink go to Instrument Control Toolbox, you will find block to send and receive data over UDP and TCP/IP. Use UDP - Read posts before to know why, Walter explained it quite well !
So with UDP blocks, you can only send final results like Data, Numbers or Graph.

If you want to send string to remote machine use command line.

You can send anything you want between machines with UDP -- as far as UDP is
concerned, it is all just a string of bytes.

One small trick to be aware of is that in Matlab char() is generally two bytes
not one (because Matlab supports Unicode).

Hello,

There are many threads that talk about similar stuff.
Walter, your description was spot on. Kudos to you for that.

For others who want to see simplified version of the same using UDP via Instrument Control Toolbox do check:

Hope that helps,
