Abaqus2Matlab是提取有限元分析程序分析结果。这个工具箱旨在提供一个有限元分析和MATLAB之间的联系,这将使有限元分析用户在MATLAB有限元分析结果进行后处理。它可以用来从一个有限元分析检索结果分析,这可以很容易地从有限元分析转移到MATLAB进行进一步处理。(Abaqus2Matlab is a program for the extraction of ABAQUS analysis results to MATLAB. It is a toolbox which aims to provide a link between ABAQUS and MATLAB, which will enable ABAQUS users to perform postprocessing of ABAQUS results in MATLAB. It can be used to retrieve results an ABAQUS analysis, which can be easily transferred ABAQUS to MATLAB for further processing. )

绘制庞加莱截面图 在相空间中适当（要有利于观察系统的运动特征和变化，如截面不能与轨线相切，更不能包含轨线）选取一截面，在此截面上某一对共轭变量如x1和x.1取固定值，称此截面为Poincare截面，相空间的连续轨迹与Poincare截面的交点成为截点。(Poincare mapping sections in the phase space properly (should be beneficial to observe the system and changes in movement characteristics, such as the cross-section can not be tangent trajectory, but also can not contain rail line) to select a cross-section, in this section for a total of conjugate variables, such as x1 and X.1 take a fixed value, call this cross-section for the Poincare section, the phase space of the continuous trajectory of the point of intersection with the Poincare cross-section to become cut-off point.)
