I have a .NET Assembly that is receiving live UDP data. I want to push that up to Matlab. I have used the .net event mechansim https://www.mathworks.com/help/matlab/matlab_external/use-net-events-in-matlab.html in the past, but I wonder if this is the lowest latency and least processing load. I expect about 10 or so 150 byte messages a second to need to be passed between the interface from .NET to Matlab, and then Matlab will have to do some parsing and display. So I want to minimize as much as possible the cost of carrying data across the barrier.

Have you considered using Instrument Control Toolbox which has native UDP capabilities?

The messages are multicast and there is protocol on top of the UDP called DIS, which I also need to handle in the C# layer, so no, I would not want to use a raw UDP toolbox. I want the coordinate framework transforms, and the dead reckonging algorithms running in C#.
