A silly question about the sream to vector block

Hi guys,

While i was trying to figure out what the stream to vector block does,I
understood that if I choose for example nitems=1024 and vector
length=1,I
get in the output 1024 vectors of 1 item each.And when I was reading
about
it
on this web page (
http://gnuradio.org/redmine/projects/gnuradio/wiki/TutorialsCoreConcepts),the
paragraph speaking about items tells exactly the opposite of what I
understood it means if nitems=1024 and vector length =1,i get in the
output
only one item which size is 1024 .I need clarification about this
subject
please!!!

best regards,
yassine

The ‘Stream To Vector’ block takes a stream of samples and makes a
vector
stream out of them. This vector stream is just the samples from the
stream
put into parallel so that for each sample you are actually sending the
vector length per second as the sample rate.

The use of the ‘Stream To Vector’ is shown in my scanoo_rx application
which takes the vector output of the ‘FFT block’ and turns it into a
stream
for use with the ‘M in N’ block.
