Hello Moritz,
Hello List,
I might have found some unintended behaviour in gr-specest. I claim that
the content of const std::vector &window is not passed in the
constructor, if called by the GRC block. I cannot explain why and ask
for hints on how to correct the behavior. I could supply a patch then.
Consider the enclosed diff against the git version of lib/Welch_impl.cc,
which basically adds some debugging output. Running this with the
original GRC block,
I get the following output:
Window created; size: 2048 (which is my FFT size) => the make(…int
window_type…) function works correctly
specest_check_arguments_impl::window.size() = 0 => this make(…, const
std::vector &window) does not get the window’s values
Constructor: 0 => the constructor(…, const std::vector &window)
does not get the window’s values, either
I suppose that this has something to do with the call-by-reference of
const std::vector, but I cannot explain why.
Can you confirm this behavior? Could you please help me finding a
solution for this an let me fix it?
Best regards
Stephan Ludwig
