## USAGE:

    rho_CT_exact = gsw_rho_CT_exact(SA,CT,p)

## DESCRIPTION:

    Calculates in-situ density from Absolute Salinity and Conservative
    Temperature.

    Note that potential density with respect to reference pressure, p_ref, is
    obtained by calling this function with the pressure argument being p_ref
    (i.e. "gsw_rho_CT_exact(SA,CT,p_ref)").

    Note that this function uses the full Gibbs function.  There is an
    alternative to calling this function, namely gsw_rho(SA,CT,p),
    which uses the computationally efficient 48-term expression for density
    in terms of SA, CT and p (McDougall et al., 2013).

## INPUT:

    SA  =  Absolute Salinity                                        [ g/kg ]
    CT  =  Conservative Temperature                                [ deg C ]
    p   =  sea pressure                                             [ dbar ]
           ( i.e. 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 & CT are MxN.

## OUTPUT:

    rho_CT_exact   =  in-situ density                             [ 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;]

    rho_CT_exact = gsw_rho_CT_exact(SA,CT,p)

    rho_CT_exact =
