Hello all,
I tried for the gaussion fit at the particular peak for the XPS data . But it didnt work it just give me straight line !! can you please help me how can I do that? The codes I tried are pasted below.
Thank you
o1s1=importdata("Co2p_002.txt");
plot (o1s1(:,1),o1s1(:,2));
x= o1s1(:,1);
fgh=flip(x);
y=o1s1(:,2)-mean(o1s1(:,2));
startPoints = [1.5 900 10 0.6]
gaussEqn = 'a*exp(-((x-b)/c)^2)+d';
f1 = fit(x,y,gaussEqn,'Start', startPoints);
plot(f1,(x),(y));
set ( gca, 'xdir', 'reverse' )
xlim([770 790])

Hello
I have the same question.
I thinks its better to use Origin pro for the XPS data.
