Functions
std::pair< Value, Value >	nk::signal::seqperiod (const Value &x, double tol=0.0, std::pmr::memory_resource *mr=nullptr)
	Find the smallest repetition period of a signal.
std::pair< Value, Value >	nk::signal::zerocrossrate (const Value &x, double level=0.0, std::pmr::memory_resource *mr=nullptr)
	Zero-crossing rate of a signal.
CusumResult	nk::signal::cusum (const Value &x, double climit=5.0, double mshift=1.0, const Value &tmean=Value::Empty, const Value &tdev=Value::Empty, std::pmr::memory_resource *mr=nullptr)
