中文说明：资源描述本代码是基于matlab编写的，主要用于计算超声导波在单层杆类结构中传播时的相速度频散曲线，代码内有很详细的注释，可读性很高，便于移植，其中的一些参数可以根据使用者具体要计算的杆类构件的的实际几何尺寸修改。
English Description：
Application backgroundThe code is written in MATLAB, mainly used to calculate the ultrasonic guided wave propagation in the single layer of the phase velocity dispersion curve, the code has a very detailed notes, very readable, easy to transplant, some of which parameters can be calculated according to the actual geometry of the user to calculate the actual geometry of the rod.
