用有限时域差分方法编写的光子晶体一个程序，计算了透射系数。( applies finite difference time domain method to analyze the band gap of Two-Dimensional cirque Photonic Crystal. )

说明：  function [ret,x0,str,ts,xts]=smg(t,x,u,flag) smg is the M-file description of the SIMULINK system named smg. The block-diagram can be displayed by typing: smg. SYS=smg(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.
