Forum: GNU Radio VOLK for outer product of two vectors?

Hi,

I looked at the VOLK to find if there are existing method to calculate 
the
outer product of two vectors, but found nothing about it.
If no, I have to write a SIMD based outer product method by myself.

Thanks,

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

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.
