基于三角形单元有限元原理，计算桁架系统在外力作用下，各节点位移与单元应变。主程序BLOCKMAT.m，从输入文件中读入结点个数，单元个数，结点荷载个数，受约束边界点数，弹性模量，泊松比，厚度，单元定义数组，结点坐标数组，结点力数组，约束信息数组。输入文件int.txt不同参数代表不同的桁架结构。(on the basis of the principle of triangle finite element calculation truss system under the action of external force, displacement of each node and element strain. MAIN program MAIN. J m, read from input file node number, cell number, number of nodal load, a constrained boundary points, elastic modulus, poisson s ratio, thickness and unit defined array, node coordinate arrays, nodal force array, array constraints information. Input file int. TXT different parameters represent different truss structure.)

《MATLAB7.0从入门到精通》对MATLAB 7.0进行了详细的介绍，力求做到细致全面。全书共分为15章。前5章是有关MATLAB的基础知识，包括MATLAB的安装、卸载及系统功能的简述，MATLAB的数学运算和数据可视化工具以及MATLAB的编程等内容。第6章～第9章是MATLAB的高级应用部分，分别介绍了MATLAB 7.0的数据分析和处理功能，符号计算功能，Simulink仿真环境和文件I/O操作。第10章～第12章和第14章介绍了信号处理工具箱、图像处理工具箱和编译工具箱以及应用广泛的高级图形设计。第13章、第15章介绍了MATLAB的外围功能，包括与Word、Excel的混合使用和MATLAB的应用程序接口。附录部分列出了常用命令和函数，Simulink的库模块和应用程序接口函数库。( MATLAB7.0 entry to the proficient on MATLAB 7.0 for a detailed description, and strive to achieve a comprehensive and detailed. The book is divided into 15 chapters. The first five chapters are on MATLAB basics, including MATLAB installation, uninstallation and brief system functions, MATLAB math and data visualization tools, and MATLAB programming and other content. Chapter 6- Chapter 9 is an advanced application part of MATLAB, introduced the data analysis and processing functions in MATLAB 7.0, symbolic computation capabilities, Simulink simulation environment, and file I/O operations. Chapter 10 ~ 12 Chapter 14 describes the Signal Processing Toolbox, Image Processing Toolbox and compilation toolkit and widely senior graphic design. Chapter 13, Chapter 15 describes the peripheral functions of MATLAB, including Word, Excel, and MATLAB mixed use application interface. The appendix lists the common commands and functions, Simulink library modules and application program interface l)

说明：  换能器三维指向性仿真研究，主要是根据仿真笛卡尔坐标系下换能器阵列的声波指向性仿真(Simulation of three-dimensional directional transducer)

成功实现计算CHzvEe算法的程序，本人测试已经通过，性能已基本达到CHzvEe算法的性能，需要MATLAB 2009b环境运行，如有问题，欢迎讨论 (The successful implementation of the program to calculate CHzvEe algorithm, I have passed the test, need MATLAB2009b operating environment, any questions, please contact me )

MATLAB和maple语言均未直接提供求解fourier级数的系数的直接函数，自己动手丰衣足食，下面提供了一个代码，大家可以参照下 (MATLAB language, and maple were not directly solve the fourier series coefficients of the direct function, it-yourself ample food and clothing, the following provides a code, we can refer to the next)

这是一种使用matlab语言实现的RLS自适应算法程序。(the realization of RLS algorithm)

信号与系统实验：gibs现象、卷积、信号的运算、网络函数！(Signal and System Experiment: gibs phenomenon, convolution, signal operations, network function!)

这是有关LTE中上行控制信道PUCCH的算法，包括调制，信道编解码等等，对学习pucch非常有用。(This is the LTE uplink control channel PUCCH in the algorithms, including modulation, channel coding and decoding, etc., to learn pucch very useful.)

说明：  把信号用数字或符号表示成序列，通过计算机或通用（专用）信号处理设备，用数值计算方法进行各种处理，达到提取有用信息的目的。(The signal using numbers or symbols into a sequence that, through the computer or general-purpose (dedicated) signal processing equipment, numerical calculation using a variety of treatment methods to achieve the purpose of extracting useful information.)
