Function pseudoVoigtTCHDerivative

pseudoVoigtTCHDerivative(
    x: number,
    fwhmG: number,
    fwhmL: number,
): { dFwhmG: number; dFwhmL: number; dx: number; fct: number }
Analytical value and partial derivatives of the TCH pseudo-Voigt function centered at x=0. The effective fwhm F and mixing mu are functions of fwhmG and fwhmL, so the derivatives chain ∂fct/∂F and ∂fct/∂mu through ∂F/∂· and ∂mu/∂·.
Parameters
- x: number
  position at which to evaluate.
- fwhmG: number
  full width at half maximum of the gaussian component.
- fwhmL: number
  full width at half maximum of the lorentzian component.
Returns { dFwhmG: number; dFwhmL: number; dx: number; fct: number }
the value fct and its partial derivatives with respect to x (dx), fwhmG (dFwhmG) and fwhmL (dFwhmL).
