JLAB is a set of Matlab functions I have written or co-written over the past fifteen years for the purpose of analyzing data. It consists of four hundred m-files spanning thirty thousand lines of code. JLAB includes functions ranging in complexity from one-line aliases to high-level algorithms for certain specialized tasks. These have been collected together and made publicly available for you to use, modify, and --- subject to certain very reasonable constraints --- to redistribute. Some of the highlights are: a suite of functions for the rapid manipulation of multi-component, potentially multi-dimensional datasets a systematic way of dealing with datasets having components of non-uniform length tools for fine-tuning figures using compact, straightforward statements and specialized functions for spectral and time / frequency analysis, including advanced wavelet algorithms developed by myself and collaborators.

With the advent of multimedia, digital signal processing (DSP) of sound has emerged from the shadow of bandwidth-limited speech processing. Today, the main appli- cations of audio DSP are high quality audio coding and the digital generation and manipulation of music signals. They share common research topics including percep- tual measurement techniques and analysis/synthesis methods. Smaller but nonetheless very important topics are hearing aids using signal processing technology and hardware architectures for digital signal processing of audio. In all these areas the last decade has seen a significant amount of application oriented research.

This is an implementation of double-array structure for representing trie, as proposed by Junichi Aoe [1]. Trie is a kind of digital search tree, an efficient indexing method with O(1) time complexity for searching. Comparably as efficient as hashing, trie also provides flexibility on incremental matching and key spelling manipulation. This makes it ideal for lexical analyzers, as well as spelling dictionaries. See the details of the implementation at [2]: http://linux.thai.net/~thep/datrie/datrie.html Historically, this was first implemented as C++ classes in a library called midatrie [2], but later simplified and rewritten from scratch in C.

Objectives The purpose of this notebook is to give you a brief introduction to the DiscreteWavelets Toolbox and show you how to use it to load images. Some basic image manipulation is illustrated as well. You will also learn how to use measures and tools such as cumulative energy, entropy, PSNR, and Huffman coding. Help on the DiscreteWavelets Toolbox Help for the toolbox is available by clicking on Help and then Product Help (or press F1) and then clicking on the DiscreteWavelets Toolbox. Several demos and examples are available as well by clicking on the Demos tab on the Help menu. Image Basics The DiscreteWavelets Toolbox comes with 18 grayscale images and 9 color images for you to use. There are three functions available to tell you more about these images. The first function is called |ImageList|. This function can tell you the names and sizes of the digital images in the Toolbox.

Parallel robotic manipulators can be considered a well-established option for many different applications of manipulation, machining, guiding, testing, control, tracking, haptic force feed-back, etc. A typical parallel robotic manipulator (PM) consists of a mobile platform connected to the base (fixed platform) by at least two kinematic chains called limbs. The mobile platform can achieve between one and three independent translations (T) and one to three independent rotations (R).

The primary goal of MySQL and Java Developer’s Guide is to provide a comprehensive approach to writing code from a Java application to a MySQL database using the industry standard: JDBC. As you will see later in this Introduction, the chapter titles indicate what area of database connectivity and manipulation they cover. The chapters are ordered to reflect the JDBC specification, but we aren’t here to simply describe the specification.

Matlab 画三维立体图形 The aim of geom3d library is to handle and visualize 3D geometric primitives such as points, lines, planes, polyhedra... It provides low-level functions for manipulating 3D geometric primitives, making easier the development of more complex geometric algorithms. Some features of the library are: - creation of various shapes (3D points, 3D lines, planes, polyhedra...) through an intuitive syntax. Ex: createPlane(p1, p2, p3) to create a plane through 3 points. - derivation of new shapes: intersection between 2 planes, intersection between a plane and a line, between a sphere and a line... - functions for 3D polygons and polyhedra. Polyhedra use classical vertex-faces arrays (face array contain indices of vertices), and support faces with any number of vertices. Some basic models are provided (createOctaedron, createCubeoctaedron...), as well as some computation (like faceNormal or centroid) - manipulation of planar transformation. Ex.: ROT = createRotationOx(THETA); P2 = transformPoint3d(P1, ROT); - direct drawing of shapes with specialized functions. Clipping is performed automatically for infinite shapes such as lines or rays. Ex: drawPoint3d([50 50 25; 20 70 10], 'ro'); % draw some points drawLine3d([X0 Y0 Z0 DX DY DZ]); % clip and draw straight line Some functions require the geom2d package. Additional help is provided in geom3d/Contents.m file, as well as summary files like 'points3d.m' or 'lines3d.m'.

最近在学习Oracle,对测试人员而言必须掌握两种语言:第一种是DML,数据操纵语言 (Data manipulation Language) 是SQL语言中,负责对数据库对象运行数据访问工作的指令集,以INSERT、UPDATE、DELETE三种指令为核心,分别代表插入、更新与删除。第二种是:DQL,数据查询语言 (Data Query Language) 是SQL语言中,负责进行数据查询而不会对数据本身进行修改的语句,这是最基本的SQL语句。核心指令为SELECT,以及一些辅助指令,如FROM、WHERE等,FROM:表示来源,可以搭配JOIN做链接查询; WHERE:过滤条件;GROUP BY:在使用聚合函数时用到,如SUM,COUNT,MAX,AVG;HAVING:对聚合结果进行筛选,这是和WHERE的不同点;ORDER BY:排序。
