Multiplicative constant vector for multiply_const_vcc

Hi,

What is the proper way to set-up the multiplicative constant vector for
multiply_const_vcc?

I tried the code below and although it compiles, upon running the
program I
get the following error:

Segmentation fault (core dumped).

The code:

std::vector<gr_complex> k;
k[0]=0.1;

blocks::multiply_const_vcc::sptr multiply_const_0 =
blocks::multiply_const_vcc::make(k);

I’ll appreciate your help.

Thank you.

Best regards,
Khalid

I think this might simply be a matter of out-of-boundary access on std::
vector. You don’t set a size on your vector at creation, so it might
have zero elements, of which you try to set the first by doing k[0].
That means you access memory that is not yet there, I.e. a segmentation
fault. Try k.push_back!

Best regards,
Marcus
