I'd like to display some values to plot. What should I do ?
A=xlsread('A.xlsx');
t=A(:,1);
i=A(:,2)/10^(2);
ft = fittype('a*exp(-x/b)+c');
F=fit(t,i,ft)
b = 1/F.b;
offset = F.c;
plot(t,i);
hold on;
plot(F)
hold off
It's an example plot, I'd like to make a plot through codes like this figure.

Hi Jaehwi
You can use text function available in MATLAB by specifying the location of text wherever you want.
txt = {'b=0.007','Offset='};
text(220,10.5,txt)
