Hello list,

currently I am looking for a way to use volk on arrays. Specifically not on input and or output buffers. So I need to align my custom arrays. How do I do this? What exactly does volk_get_alignment and set_alignment do? I didn't find any documentation or source code yet.


//define arrays like this:
int size = 10; // or what so ever.
gr_complex my_array1[size];
gr_complex my_array2[size];
gr_complex my_array3[size];

volk_32fc_x2_multiply_32fc_a(my_array3, my_array2, my_array1, size);

Is it possible to do something like this? Or am I on the wrong way?

Thanks in advance!
