Description: hurst指数估计
This function does dispersional analysis on a data series, then does a
Matlab polyfit to a log-log plot to estimate the Hurst exponent of the
series.
This algorithm is far faster than a full-blown implementation of Hurst s
algorithm. I got the idea from a 2000 PhD dissertation by Hendrik J
Blok, and I make no guarantees whatsoever about the rigor of this approach
or the accuracy of results. Use it at your own risk.

Description: polyfit函数是matlab中用于进行曲线拟合的一个函数。其数学基础是最小二乘法曲线拟合原理。曲线拟合:已知离散点上的数据集,即已知在点集上的函数值,构造一个解析函数(其图形为一曲线)使在原离散点上尽可能接近给定的值。(The polyfit function is a function used in curve fitting in matlab. Its mathematical basis is the principle of least-squares curve fitting. Curve fitting: Known data sets at discrete points, known as function values on the point set, construct an analytical function (the graph is a curve) so that the original discrete point is as close as possible to a given value.)

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)
