function [t0,e]=Gauss1(fmax)

%Gauss1 function
%E(t)=exp(-4*pi*(t-t0)^2/tao^2);
%On the t0 point,the value of Gauss reaches the top.
%ofen ,tao=2/fmax ,t0=0.8*tao,fmax is the frequency of Source;
%dt=1/40*fmax;  look the k valve for Gauss zero point.
%To execute this M-file, type "[t0,e]=Gauss1(fmax)" at the MATLAB command window;
%fmax is the frequency of Gauss which you want to input;
%for example, [t0,e]=Gauss1(10^10).

tao=2/fmax;
tao=tao*40*fmax;
t0=0.8*tao;
t=0:1:2*t0;
e=exp(-4*pi*(t-t0).^2/tao^2);
plot(t,e);
