17 Apr 2012 Lorentzian fit LORENTZFIT fits a single- or multi-parameter Lorentzian function to data Author: Jered Wells

Yea, Thanks for the script. It was very helpful

17 Apr 2012 Lorentzian fit LORENTZFIT fits a single- or multi-parameter Lorentzian function to data Author: Jered Wells

I changed the 3 parameter fitting fucntion to
F= p(4) + (2*p(1)./pi)*(p(3)./(4*(x-p(2)).^2 + p(3).^2))

now p1 gives Area, p2 gives the center, p3 gives the FWHM and p4 gives the y offset.

I tried this function on my data and found that parameter calculated are very different from the one I get from Orgin.

I recalculated the width by taking the sq. root of P3. Is that the correct way ?
