当前学界中已有的三种通过复杂网络理论分析时间序列的方法（VG、HVG、LPVG）都能够继承时间序列的基本特征，但相应性能例如抗噪以及算法复杂度等都有一 定的局限性 。因此，本文在已有三种方法的基础上提出另外两种可视图建网方法（LPHVG和DLPVG）。-Methods (VG, HVG, LPVG) already in the academic world through a complex network theory of three sequence analysis time are

Each code generates GIF files of group/phase velocity animations where vp>vg, vp=vg, and vp<vg. In the animation, two markers are used to show the movements of the wavepacket and envelope.

通过西奥道森气动力模型求解气动力，并通过v-g法求解颤振速度与颤振频率(Solve the aerodynamic force through the Theodorsen aerodynamic model and solve the flutter velocity and flutter frequency through the v-g method)
