		 NFFT~3 is a software library that
		 implements the nonequispaced fast Fourier
		 transform (NFFT) and a number of related
		 algorithms, e.g. nonequispaced fast
		 Fourier transforms on the sphere and
		 iterative schemes for inversion. This is
		 to provide a survey on the mathematical
		 concepts behind the NFFT and its variants,
		 as well as a general guideline for using
		 the library. Numerical examples for a
		 number of applications are given.",
