apply_rectangular()

MAYAFLUX_API void MayaFlux::Kinesis::Discrete::apply_rectangular ( std::span< double >  data, size_t  support = std::numeric_limits< size_t >::max(), size_t  offset = 0  )

noexcept

Apply a rectangular taper in-place without materialising coefficients.

Zeroes everything outside the support region and leaves the region itself untouched, since its coefficients are unity. The default arguments gate nothing and leave data unchanged.

Parameters

data	Target span (modified in place)
support	Width of the unity region; defaults to the full length
offset	Index where the unity region begins
