R语言有各种各样的数据类型,包括标量scaler、向量vector(数值向量、字符串向量、逻辑向量)、矩阵matrix、dataframe和列表list。 R语言使用c函数创建向量(Vector、数值向量、字符串向量、逻辑向量)、使用c函数和方括号索引(index)向量的内容、vector向量实战 a <- c(1,2,5.3,6,-2,4) # numeric ...

Note that when the effective index contrast between core and cladding regions is large, the weak-guidance (scalar) approximation breaks down, leading to inaccurate results, and it is often necessary to adopt a vectorial method that includes polarization effects. This is typically necessary when the...

语法：lookup(lookup_value,lookup_vector,result_vector)示例：在查找"万兰"的订单号时，数据源无法通过vlookup或hlookup匹配，因为姓名列位于最后一列。此时，使用lookup函数在F2单元格输入“=LOOKUP(E2,C:C,A:A)”。第一个参数为查找的数值，第二个参数查找"万兰"在C列中的位置（第七行），结合...

Based on the Galerkin's method, a numerical method is developed to analysis the cutoff frequencies of guided modesof optical waveguides with arbitrary refractive index profile. Solutions are presented in the quasi-vector regime.Optical waveguide structures with single core of arbitrary shape are conside...
