Having your complete general_work function wouldn't have hurt my
understanding much...
I really can't make out what you're trying to do without doubt.
Anyway, from the code below I think "in" *must at least* have the same
number of entries that your for loop has iterations; did you just try using
d_group * N_FS(d_normal) instead of d_N_phich_group * N_FS_phich(d_normal_cp)
when allocating your array?
It seems to me that having two ways to determine how many inputs there is a
likely cause for mistake. Use the size() of the input_items to determine how
many inputs you really have, and assert(input_items.size() ==
number_of_inputs_like_I_calculate_it); to make sure things line up.
Also, the whole process seems unnecessary, since you do nothing more than
copying the pointers from input_items to in; the typecast is nothing but
syntactic magic and can be done by having "in = ((const gr_complex*)*)
input_items;"; also, I encourage you to use the C++-style explicit cast
operators (in this case, reinterpret_cast<>) for their clarity, but that's more
a question of personal liking :)
Greetings,
Marcus
