D'oh! Thanks that did the trick. For everyone who is interested, this is
the snippet of working code:
gr_complex *out = (gr_complex *) output_items[0];
int noi = noutput_items;
gr_complex temp1[noi];
gr_complex temp2[noi];
// do something with temp1 and temp2
volk_32f_x2_add_32f_a((float *)out, (float *)temp1, (float *)temp2, 2*noi);
Best regards,
Gerald

Just add the complex stream as floats and multiply the length of the

Hi list,
I am currently trying to wrap my head around volk and have some
questions concerning orc.
- Is writing an *.orc file and adding it to the appropriate header
under volk/include/volk/ everything that has to be done to get an
initial volk kernel?
- If I am using orc, do I still have to write a general fallback
function in pure c++?
The reason why I want to write a volk kernel is, that I need to
add two complex vectors. I was only able to find a volk kernel for
float vectors. Am I missing something? Adding two complex vectors
seems to be such a basic and obvious operation, is there some kind
of workaround or a better alternative?
Thanks a lot,
Gerald
