Classes
class	SincTableManager
	A manager used for constructing the table necessary for Sinc interpolations. The manager creates one table per design and provides its as necessary A table contains shifted, stretched KaiserWindow functions in both directions. More...
class	SincTableManager::Table
class	SincInterpolator
	A sinc interpolator for bandlimited uniformly-sampled functions y(x). Interpolators can be designed for any two of three parameters: maximum error (emax), maximum frequency (fmax) and maximum length (lmax). The parameter not specified is computed when an interpolator is designed. More...
