Re: [Discuss-gnuradio] VOLK for outer product of two vectors?

[Alex Zhang]

Hi Tom,

My current solution, due to my limited developing time,  is to reuse the volk_32fc_x2_multiply_conjugate_32fc_a to compute the outer product, instead of writing a separate outer product method.  It works well.

Alex,
I don't believe there is a VOLK kernel that does that. But this is why
VOLK is designed to be extensible for when you need to write your own.

If you do come up with a new outer product kernel, please consider
giving it back to the VOLK product.

Thanks,
Tom
