FreeFEM is an implementation of the GFEM language dedicated to the finite element method. It provides you a way to solve Partial Differential Equations (PDE) simply. Although you can solve quite complicated problems can be solved also.

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

可以完成各类坐标之间的大地高斯以及经纬度坐标转换，用户可以通过MFC界面完成坐标的读取、输入，从而获取需要的坐标

资源描述 先来明确一下概念：一个逻辑表达式如果对于其变元的任一种取值均为真，则成为重言式；反之，如果对于其变元的任一种取值都为假，则称为矛盾式，然而，更多的情况下，既非重言式，也非矛盾式。 对于一个逻辑表达式，到底属于上面三种情况的哪一种，可以有很多种判断方法，如真值表法，直接证明法等等，这些你可以参考 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报

c语言程序 求和C语言是一种计算机程序设计语言，它既具有高级语言的特点，又具有汇编语言的特点。它由美国贝尔实验室的Dennis M. Ritchie于1972年推出，1978年后，C语言已先后被移植到大、中、小及微型机上，它可以作为工作系统设计语言，编写系统应用程.
