## USAGE:

    specvol = gsw_specvol(SA,CT,p)

## DESCRIPTION:

    Calculates specific volume from Absolute Salinity, Conservative
    Temperature and pressure, using the computationally-efficient 48-term
    expression for density (McDougall et al., 2011).

## INPUT:

    SA  =  Absolute Salinity                                        [ g/kg ]
    CT  =  Conservative Temperature                                [ deg C ]
    p   =  sea pressure                                             [ dbar ]
           (ie. absolute pressure - 10.1325 dbar)

    SA & CT need to have the same dimensions.
    p may have dimensions 1x1 or Mx1 or 1xN or MxN, where SA and CT are MxN.

## OUTPUT:

    specvol  =  specific volume                                   [ kg/m^3 ]

## EXAMPLE:

    SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
    CT = [28.8099; 28.4392; 22.7862; 10.2262;  6.8272;  4.3236;]
    p =  [     10;      50;     125;     250;     600;    1000;]

    specvol = gsw_specvol(SA,CT,p)

    specvol =
