# gsw_specvol_from_pot_enthalpy_ice_poly

`specific volume from potential enthalpy of ice (polynomial)`

## 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 =`
