I'd like to implement the receiving end of my system in MATLAB - this requires Gigabit Ethernet with sustained speeds of over 200Mb/sec.
Using MATLAB's built-in UDP from the Instrument Control Toolbox does not appear to be sufficient. Are there any good alternatives?
If the data can be put into batches:
Use an external program to download the data to your computer, and save it to a file. Then, Matlab can read from that file whenever it needs more data. That way you partition the problem into two manageable pieces - and if you're using a decent OS, the file will never leave RAM so you won't have to worry about speed.
If you know Java, you can write the networking part of your code in Java classes, load those into your Matlab session with javaclasspath(), and invoke them from M-code. This could transform the problem from getting the data through Matlab's udp() function to getting the data across the Java/Matlab boundary.
