快速傅立叶的变换-the Fast Fourier Transform

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, Bilkent Univ., 1998 and an algorithm described by S.C. Pei, M.H. Yeh, and C.C Tseng: Digital fractional Fourier transform base

The Free Finite Element Package is a library which contains numerical methods required when working with finite elements. The goal of FFEP is to provide basic functions for approximating the solution of elliptic and parabolic PDEs in 2D.

在数值计算中，一般的牛顿迭代法得到的数值具有截断误差，因此，用VB编写的可是实现任意精度的圆周率的计算程序-in numerical calculation, the general Newton iterative numerical method with the truncation error, therefore, prepared by the VB But to achieve any degree of accuracy the circumference of the rate calculation procedures
