Receive UDP data from multiple sources in Matlab

Question

I need to set up a UDP reader in Matlab that receives data from a number of sources. I typically use this for a single data source:

[packet,~,~,senderaddress]=fread(s,s.BytesAvailable)

The problems are that I want to avoid waiting for the timeout, I don't have terminated data arriving, and packets are of unknown sizes. Has anyone else had this problem? Thanks

Answer 1

Why not using Java's networking capabilities. UDP File Exchange does some Java scripting to access a UDP socket. Define the max size of your packets (UDP datagrams can be up to 65536 bytes long) and the preferred timeout.
