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

在数据库中发现频繁模式和关联规则是数据挖掘领域的最基本、最重要的问题。大多数早期的研究采用了类似Apriori算法的产生候选级并测试迭代的途径代价是昂贵的,尤其是挖掘富模式和长模式时,Jiawei Han提出了一种新颖的数据结构FP_tree,及基于其上的FP_growth算法,主要用于有效的进行长模式与富模式的挖掘.本文在讨论了FP_growth算法的基础上,提出了用Visual C++实现该算法的方法,并编写了算法的程序。-found in the database model and the frequent association rules is the area of data mining the most fundamental and important issues. Most of the early studies used a similar Apriori algorithm for the selection of candidates and test-iterative way was costly, particularly mining the rich patterns and long model, Jiawei Han proposed a novel data structure FP_tree and on the basis of their FP_growth algorithm used effectively the model for long and rich patterns of excavation. This paper discussed the FP_growth algorithm on the basis of the Visual C of the algorithm, and the preparation procedure of the algorithm.

convex hull算法模板
本算法采用了分治和递归相结合的方法,基本思想是:先求出在矩形边界上的点,这些点是组成凸 壳的点集的子集,然后根据这些点分别求出位于边界矩形四个角上属于凸壳的点,最后合并得到凸壳。 本算法在计算过程中逐步缩小点的查找范围 ,因此其优越性在海量数据求凸壳时更明显。
