[Discuss-gnuradio] scalar and vector streams

[Vincenzo Pellegrini]

hello, 
first of all thanks to everybody in the list for the huge amount of
suggestions about hard-disk reading speeds I was provided with a few
days ago. :)

then another question: which is the wisest way to convert a scalar
stream to a vector stream and then back to a scalar stream within a
python flow graph.. if there is one, of course! 

what I'm trying to do is: 
       
             source_c--->gr.fft_vcc--->rest_of_the_flow_graph_c

is this reasonable?


best regards
vincenzo
