## USAGE:

    osmotic_pressure_t_exact  =  gsw_osmotic_pressure_t_exact(SA,t,p)

## DESCRIPTION:

    Calculates the osmotic pressure of seawater.

    Click for a more detailed description of calculating
    the osmotic pressure of seawater.

## INPUT:

    SA =  Absolute Salinity                                         [ g/kg ]
    t  =  in-situ temperature (ITS-90)                             [ deg C ]
    p  =  sea pressure                                              [ dbar ]
          ( i.e. absolute pressure - 10.1325 dbar )

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

## OUTPUT:

    osmotic_pressure_t_exact  =  osmotic pressure of seawater       [ dbar ]

## EXAMPLE:

    SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
    t =  [28.7856; 28.4329; 22.8103; 10.2600;  6.8863;  4.4036;]
    p =  [     10;      50;     125;     250;     600;    1000;]

    osmotic_pressure_t_exact = gsw_osmotic_pressure_t_exact(SA,t,p)

    osmotic_pressure_t_exact =
