[matlab] EmFDTD-v1.2r1

Description: 外国人开发的电磁时域有限差分方法工具包 Electromagnetic Finite-Difference Time-Domain (EmFDTD) is a basic two-dimensional FDTD code developed at the School of Electrical Engineering, Sharif University of Technology. This code has been written based on the standard Yee s FDTD algorithm. Applications include propagation, scattering, and diffraction of electromagnetic waves in homogeneous and non-homogeneous isotropic media for in-plane propagating waves. Negative permittivites or permeabilities as well as dispersion is not included. Zero, Periodic, and Perfectly Matched Layer boundary conditions may be selectively applied to the solution domain. The program is best suited for study of propagation and diffraction of electromagnetic waves in Photonic Crystal structures. EmFDTD is written in MATLAB language and has been tested under MATLAB 5.0 and higher versions.-Foreigners developed electromagnetic FDTD method Toolkit Electromagnetic Finite-Difference Time-Domain (EmFDTD) is a basic two-dimensional FDTD code developed at the School of Electrical Engineering, Sharif University of Technology.

[matlab] Dijkstra

Description: 最短路径的Dijkstra算法程序。Dijkstra算法是典型最短路算法，用于计算一个节点到其他所有节点的最短路径。主要特点是以起始点为中心向外层层扩展，直到扩展到终点为止。Dijkstra算法能得出最短路径的最优解，但由于它遍历计算的节点很多，所以效率低。 　　Dijkstra算法是很有代表性的最短路算法，在很多专业课程中都作为基本内容有详细的介绍，如数据结构，图论，运筹学等等。 -The Dijkstra shortest path algorithm for the procedure. Dijkstra algorithm is a typical shortest path algorithm, used to calculate a node to all other nodes of the shortest path. The main characteristics is the starting point as the center outward expansion layers, until the end date be extended to. Dijkstra shortest path algorithm can arrive at the optimal solution, but because of its calculation of the node traversal, so inefficient. Dijkstra algorithm is very representative of the shortest path algorithm, in many professional courses in the basic content as described in detail, such as data structures, graph theory, operational research and so on.

[matlab] dsatbx

Description: matlab数据结构 算法工具箱, 包括堆栈 队列 2叉树 红黑树 -Data Structures & Algorithms Toolbox ==================================== The Data Structures & Algorithms Toolbox provides advanced data structures and algorithms for the Matlab(r) 5 environment. It implements functions to create and destroy singly and doubly linked list, stack, queue, binary tree and red-black (balanced) binary tree. Data elements can be inserted, deleted or searched for. A graphical representation of trees can be shown. All algorithms are clearly written as m-files, which allows the toolbox to be used as a teaching aid in educational data structures courses. This is the first implementation available of advanced datatypes, common in other languages, for Matlab.

Description: 基于对指纹的完整脊状结构的显式检测的表征。 在指纹上有丰富的歧视性信息的重要组成部分。当地的脊 结构不能完全以细节为特征。这个基于过滤的算法使用了一个Gabor过滤器来捕获本地和全局的细节。 指纹作为一种紧凑的固定长度的指纹。指纹匹配是基于欧几里德的。 两个对应的指纹之间的距离是非常快的。我们能够实现a。 验证精度仅略低于基于细节的算法的最佳结果。 发表在开放文学。我们的系统比先进的基于细节的系统性能更好。 当应用系统的性能要求不要求非常低的错误接受率时。 最后，我们证明了匹配的性能可以通过结合配对的决定来提高。 基于互补(基于细节和基于过滤的)指纹信息。(With identity fraud in our society reaching unprecedented proportions and with an increasing emphasis on the emerging automatic personal identification applications, biometrics-based verification, especially fingerprint-based identification, is receiving a lot of attention. There are two major shortcomings of the traditional approaches to fingerprint representation. For a considerable fraction of population, the representations based on explicit detection of complete ridge structures in the fingerprint are difficult to extract automatically. The widely used minutiae-based representation does not utilize a significant component of the rich discriminatory information available in the fingerprints.)
