function [a,g0] = getExpontialModel(f)
A = zeros(1,length(f)-1);
G_0 = zeros(1,length(f)-1);
for i=2:length(f)
if f(i-1) ~= 0
A(i-1) = f(i)/f(i-1);
else
A(i-1) = 1;
end
end
a = median(A); %more robust than mean function
for i=1:length(f)-1
G_0(i) = f(i)/a^i;
end
g0 = median(G_0);%more robust than mean function
