## USAGE:

    entropy_ice  =  gsw_entropy_ice(t,p)

## DESCRIPTION:

    Calculates specific entropy of ice.

## 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:

    entropy_ice  =  specific entropy of ice                     [ J/(kg*K) ]

## EXAMPLE:

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

    entropy_ice = gsw_entropy_ice(t,p)

    entropy_ice =
