Constructor & Destructor Documentation

InterpolatedDerivatives()

StellarEvolution::InterpolatedDerivatives::InterpolatedDerivatives	(	double	mass,
		double	feh,
		std::vector< const FunctionDerivatives *> *	derivatives,
		const alglib::real_1d_array &	interp_masses,
		const alglib::real_1d_array &	interp_feh,
		double	age = NaN,
		bool	log_quantity = false,
		bool	delete_derivatives = false
	)

Create an object that interpolates derivatives from evolution tracks.

The input grid of derivatives may be of quantity of log(quantity) vs. age or log(age). The returned derivatives are always of quantity vs age (no log of anything).

Parameters

mass	The stellar mass at which to evaluate the interpolated derivatives.
feh	The stellar [Fe/H] at which to evaluate the interpolated derivatives.
derivatives	The derivatives at each grid intersection.
interp_masses	The masses of the grid intersections.
interp_feh	The sorted [Fe/H] of the grid intersections.
age	If not NaN, derivatives are assumed to calculate derivatives w.r.t. ln(age), whereas this object always returns derivatives w.r.t. age.
log_quantity	Are derivatives of log(quantity) instead of quantity?
delete_derivatives	Should derivatives be deleted when this object is destroyed?
