Thanks! As I see you apply it to the first element of x as in  volk_32fc_something_32fc(&x[0], ...);. I want to multiply the whole vector like as a inner product of two vectors. Is it possible? - NE Четверг, 20 марта 2014, 10:28 -04:00 от Tom Rondeau : >On Thu, Mar 20, 2014 at 10:09 AM, Adity

Hi all, I am using ubuntu 13.04, GNUradio 3.7.  I have a question related to VOLK library.  When I create a vector, lets say: vector y1; Can I multiply this vector to another vector using VOLK? Is there any good documentation for this? -- NE___ Dis
