## USAGE:

    pot_enthalpy = gsw_pot_enthalpy_from_pt_ice_poly(pt0_ice)

## DESCRIPTION:

    Calculates the potential enthalpy of seawater from potential
    temperature (whose reference sea pressure is zero dbar). This is is a
    computationally efficient polynomial fit to the potential enthalpy of
    ice.

## INPUT:

    pt0_ice  =  potential temperature of ice (ITS-90)              [ deg C ]

## OUTPUT:

    pot_enthalpy_ice  =  potential enthalpy of ice                  [ J/kg ]

## EXAMPLE:

    pt0_ice = [-10.7856; -13.4329; -12.8103; -12.2600; -10.8863; -8.4036;]

    pot_enthalpy_ice = gsw_pot_enthalpy_from_pt_ice_poly(pt0_ice)

    pot_enthalpy_ice =
