rectangular()

MAYAFLUX_API std::vector< double > MayaFlux::Kinesis::Discrete::rectangular	(	size_t	n,
		size_t	support = std::numeric_limits< size_t >::max(),
		size_t	offset = 0
	)

Rectangular (boxcar) taper coefficients.

Unity across a contiguous support region, zero elsewhere. The default arguments give unity across the whole length, which is the identity taper; a narrower support gates a region and suppresses the rest, which is the form used for frame extraction, impulse response truncation, and segment isolation ahead of a transform.

A support of 0 yields an all-zero vector. An offset at or beyond n leaves no unity region.

Parameters

n	Length in samples
support	Width of the unity region; defaults to the full length
offset	Index where the unity region begins

Returns

Coefficient vector of length n
