计算阶跃折射率光纤传播常数、归一化频率、截止波长、导模数量等- Calculate for Step Index Fibers (using MATLAB): a) Propagation constant (β) b) Normalized propagation constant (b) c) V number (V) d) Check whether the fiber is single mode or multi mod

光纤模式容量，以及归一化。并用此对单模光纤进行模式分析(Fiber mode capacity, and normalization. The mode analysis of single mode fiber is also used.)
