a = lorentzfit1(x,y,a0) LORENTZFIT1 fits the input Y(X) with a Lorentzian function of the form Y'(X) = 1./(A(X.^2 + 1)) (i.e. 1-parameter model). INPUTS X : Independent variable values Y : Dependent variable values [Y(X)] OPTION A0 : Define initial guess for parameter A OUTPUT A : Lorentzian parameters A EXAMPLE x = -16:0.1:35; y = 1./15.8./(x.^2 + 1) + randn(size(x))./10; a = lorentzfit1(x,y); Jered R Wells 11/15/11 jered [dot] wells [at] duke [dot] edu See also: lorentzval1, lorentzfit REF: http://www.home.uos.de/kbetzler/notes/fitp.pdf REF: Siewerdsen, et al., (1998).
