apply_taper()

void MayaFlux::Kinesis::Discrete::apply_taper ( std::span< double >  data, std::span< const double >  taper  )

noexcept

Multiply data element-wise by a precomputed taper.

Applied cyclically if taper is shorter than data; truncated if longer. The common case (equal sizes) is a straight element-wise multiply.

Parameters

data	Target span (modified in place)
taper	Coefficient span
