Re: [Discuss-gnuradio] How to use stream_mux in C++

[Robert Kraml]

Thanks for the pointer Martin.  I would likely not have guessed that was 
what that block is used for.  I was about to turn my attentions to the 
director block but I had read there were issues with switching that one.

 I was able to figure out how to use that multiply_matrix block with 
its vector of vectors and it seems to be working fine!
