FEM-waveguide-using-MATLAB
This paper shows how electrical engineering undergraduates can acquire a working
knowledge of the finite element method (FEM) within a short period of time using MATLAB. For
simplicity, only first-order triangular elements are considered. The scalar wave equation for
homogeneous isotropic waveguides is used for introducing the FEM. Simple waveguide problems,
including a design problem, are discussed as examples. It is shown how the knowledge acquired can
be extended to other electromagnetic problems

GMDH_main为GMDH主函数；
variable_Combin为输入层初始变量选为x1,x1^2,x1*x2,x2^2,x2时的输入变量矩阵值
variable_select计算X_train训练输入数据,Y_train训练输出数据,X_test测试输入数据,Y_test测试输出数据
Combin为求变量的两两组合
Sym_Combin为求符号变量的两两组合
PE_AIC求每层各神经元的参数估计W，及训练数据在参数估计后估计的输出out_train，测试数据在参数估计后的估计输出out_test，还有与实际比较的误差平方和PESS， 以及准则值AIC
sym_representation求最终的输入输出符号表达式
Criterion_value求准则值
