Description: 1、根据LP01模V和W的数值，拟合例题中V在[1.5，2.4]区间的V和W的线性关系式，并给出拟合得到的最大误差。（提示：利用函数polyfit(),polycal()）
2、说明三个传输常数U、V、W以及简并模的概念和意义。
3、结合仿真结果（包括例题中的仿真结果）阐述U、V、W对导波的影响。
提示：模式截止、模式远离截止等等(1. According to the values of LP01 modulus V and W, the linear relationship between V and W in [1.5, 2.4] of the fitting example is fitted, and the maximum error of the fitting is given. (hint: use the function polyfit(), polycal())
2. The concept and significance of three transmission constants u, V, W and degenerate modules are explained.
3. Combined with the simulation results (including the simulation results in the example), the influence of u, V and w on the guided wave is described.
Tip: mode cutoff, mode away from cutoff, etc)
