## USAGE:

    CT = gsw_CT_from_pt(SA,pt)

## DESCRIPTION:

    Calculates Conservative Temperature of seawater from potential
    temperature (whose reference sea pressure is zero dbar).

    Click for a more detailed description of calculating
    Conservative Temperature from potential temperature.

## INPUT:

    SA  =  Absolute Salinity                                        [ g/kg ]
    pt  =  potential temperature (ITS-90)                          [ deg C ]

    SA & pt need to have the same dimensions.

## OUTPUT:

    CT  =  Conservative Temperature                                [ deg C ]

## EXAMPLE:

    SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
    pt = [28.7832; 28.4209; 22.7850; 10.2305;  6.8292;  4.3245;]

    CT = gsw_CT_from_pt(SA,pt)

    CT =

     28.809923015982083
     28.439144260767169
     22.786246608464264
