MATLAB矩阵位移法计算桁架节点位移，结构力学大作业(Calculation of displacement of truss joints by MATLAB matrix displacement method)

说明：  D3插件和DD145插件，都是RSR为基础修改的，若有兴趣可以试试。(D3 plug-in and DD145 plug-in are both RSR-based modifications, if interested, you can try.)

很好的opencv入门文档，后续上传其他相关-good opencv entry documents, the follow-up to other relevant Upload

说明：  本书是一本"围绕练习来学习”的图书，特别适合作为大专院校的实验教材或者是自学用书。全书涉及的内容除了LabVIEW的基本编程概念和方法之外，还有大量的章节讨论DAQ的使用及LabVIEW的应用。全书共分13章，内容包括while循环与波形图、for循环与波形图、MathScript模型与XY图、DAQ辅助数据采集、数据文件与字符串、移位寄存器、case结构、数据独立性与序列结构、vi分析、使用DAQmx vi的数据采集与生成、PID温度控制项目、独立仪器控制等。(This book is a "learning around practice" book, especially suitable for college experimental teaching materials or self-study books. In addition to the basic programming concepts and methods of LabVIEW, there are also a large number of chapters to discuss the use of DAQ and the application of LabVIEW. The book is divided into 13 chapters, including while loop and waveform diagram, for loop and waveform diagram, MathScript model and XY diagram, DAQ auxiliary data acquisition, data file and string, shift register, case structure, data independence and sequence structure, VI analysis, data acquisition and generation using daqmx VI, PID temperature control project, independent instrument control, etc.)
