Function generalizedLorentzianDerivative

generalizedLorentzianDerivative(
    x: number,
    fwhm: number,
    gamma: number,
): { dFwhm: number; dGamma: number; dx: number; fct: number }
Analytical value and partial derivatives of the generalized lorentzian function centered at x=0.
Parameters
- x: number
  position at which to evaluate.
- fwhm: number
  full width at half maximum.
- gamma: number
  kurtosis parameter of the shape.
Returns { dFwhm: number; dGamma: number; dx: number; fct: number }
the value fct and its partial derivatives with respect to x (dx), fwhm (dFwhm) and gamma (dGamma).
