## USAGE:

CT_maxdensity_exact = gsw_CT_maxdensity_exact(SA,p)

## DESCRIPTION:

Calculates the Conservative Temperature of maximum density of seawater.
This function returns the Conservative Temperature at which the density
of seawater is a maximum, at given Absolute Salinity, SA, and sea
pressure, p (in dbar).

Note that this function uses the full Gibbs function. There is an
alternative to calling this function, namely gsw_CT_maxdensity(SA,p),
which uses the computationally efficient 75-term expression for
specific volume in terms of SA, CT and p (Roquet et al., 2015).

## INPUT:

SA = Absolute Salinity [ g/kg ]
p = sea pressure [ dbar ]
( i.e. absolute pressure - 10.1325 dbar )

p may have dimensions 1x1 or Mx1 or 1xN or MxN, where SA is MxN.

## OUTPUT:

CT_maxdensity_exact = Conservative Temperature at which the density
of seawater is a maximum for given Absolute
Salinity and pressure. [ deg C ]

## EXAMPLE:

SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
p = [ 10; 50; 125; 250; 600; 1000;]

CT_maxdensity_exact = gsw_CT_maxdensity_exact(SA,p)

CT_maxdensity_exact =
