将求解偏微分方程和局部网格加密简单组合在了一起。用的方程是一个含有间断二次系数的椭圆型方程，在系数间断的位置，解会有一个弱间断。-Will solve the partial differential equations and local mesh refinement simple combinations together. Used equation is a quadratic coefficient of containing discontinuous elliptic equations, the location of discontinuity in the coefficient, there will be a weak solution of continuity.

这是一份基于c++实现的查找二叉树(排序二叉树)的实现代码。在源代码类中，包含二叉查找树的插入，删除，以及查找树中任意排序任意位置的数。其中函数包含了递归实现和非递归实现。

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
