用matlab读取大智慧数据下载的.day文件，得到股票数据。(Matlab read with great wisdom of data downloaded. Day paper, the stock data.)

本文基于大型通用有限元软件ANSYS和MATLAB,探索三维实体模型下进行PC桥梁结构整体仿真分析的途径,研究其关键理论及专业模块开发技术。重点研究了预应力筋的模拟、预应力效应的等效转换和桥梁截面切片技术。研究成果可广泛应用于PC桥梁的三维仿真领域,具有较大的理论意义和工程实用价值。对写这方面研究很有帮助(Based on large-scale general-purpose finite element software ANSYS and MATLAB, explore the three-dimensional solid model of the bridge structure under the PC way to the overall simulation analysis to study the key theoretical and professional development of technology modules. Focused on the tendons of the simulation, the equivalent effect of prestressed bridge conversion and cross-section slicing. Research results can be widely used in PC bridges the field of three-dimensional simulation with the larger theoretical and practical engineering value. Research in this area to write very helpful)
