Description: 详细表述了分数阶傅立叶变换的离散实现，将现有的算法进行比较。-In this note we make a critical comparison of some matlab programs for the digital computation of the
fractional Fourier transform that are freely available and we describe our own implementation that lters
the best out of the existing ones. Two types of transforms are considered: First the fast approximate
fractional Fourier transform algorithm for which two algorithms are available. The method is described
in H.M. Ozaktas, M.A. Kutay, and G. Bozdagi. Digital computation of the fractional Fourier transform.
IEEE Trans. Signal Process., 44:2141{2150, 1996. There are two implementations: one is written by
A.M. Kutay the other is part of package written by J. O Neill. Secondly the discrete fractional Fourier
transform algorithm described in the master thesis C . Candan. The discrete fractional Fourier transform,
