Different edfs simulations from esfit and pepper
Posted: Wed Aug 22, 2018 4:06 pm
Hello,
I've been getting different simulated edfs spectra from esfit and pepper simulation using the same parameter. I'm not quite sure what I did wrong, here are the scripts and pictures:
Thanks for your time!

[x,y1] = pepper(Sys,Exp);
minVal = min(y1);
maxVal = max(y1);
norm_data = (y1 - minVal)/(maxVal - minVal);
plot(x,norm_data,'LineWidth',1,'Color','b')
hold on
plot(B/10,real(norm_spec),'LineWidth',1)
hold off
%these limits just help you define the size of window it provides%
