## USAGE:

    gsw_alpha_wrt_t_ice = gsw_alpha_wrt_t_ice(t,p)

## DESCRIPTION:

    Calculates the thermal expansion coefficient of ice with respect to
    in-situ temperature.

## INPUT:

    t   =  in-situ temperature (ITS-90)                            [ deg C ]
    p   =  sea pressure                                             [ dbar ]
           ( i.e. absolute pressure - 10.1325 dbar )

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

## OUTPUT:

    alpha_wrt_t_ice  =  thermal expansion coefficient of ice         [ 1/K ]
                        with respect to in-situ temperature

## EXAMPLE:

    t = [-10.7856; -13.4329; -12.8103; -12.2600;  -10.8863;  -8.4036;]
    p = [      10;       50;      125;      250;       600;     1000;]

    alpha_wrt_t_ice = gsw_alpha_wrt_t_ice(t,p)

    alpha_wrt_t_ice =
