           fitmodel

           x         - Input x value array. Should be double precision.
           parameter - Parameter to compute model. Must contain 2
                       values.

           lorentz:x0    - Center of the Lorentzian curve (mean value)
           lorentz:gamma - Half-width factor of Lorentzian curve.

           y =  1/pi * gamma/2 * 1/((x-x0)^2 + (gamma/2)^2)

           None
