## USAGE:

    specvol_ice = gsw_specvol_from_pot_enthalpy_ice_poly(pot_enthalpy_ice,p)

## DESCRIPTION:

    Calculates the specific volume of ice from potential enthalpy
    of ice.  The reference sea pressure of the potential enthalpy is zero
    dbar.

    Note that this is a computationally efficient polynomial version of
    potential enthalpy from specfic volume of ice.

## INPUT:

    pot_enthalpy_ice  =  potential enthalpy of ice                 [ J/kg ]
    p  =  sea pressure                                             [ dbar ]
           ( i.e. absolute pressure - 10.1325 dbar )

    p may have dimensions 1x1 or Mx1 or 1xN or MxN, where pot_enthalpy_ice
    is MxN.

## OUTPUT:

    specvol_ice  =  specific volume of ice                        [ kg/m^3 ]

## EXAMPLE:

    pot_enthalpy_ice = ...
    [-3.5654e5;-3.6195e5;-3.6085e5;-3.5902e5;-3.5629e5;-3.5159e5]
    p = [     10;      50;     125;     250;     600;    1000;]

    specvol_ice = gsw_specvol_from_pot_enthalpy_ice_poly(pot_enthalpy_ice,p)

    specvol_ice =
