gsw_infunnel

"oceanographic funnel" 
check for the 25-term equation

Contents

USAGE:

in_funnel = gsw_infunnel(SA,CT,p)

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 & CT are MxN.

OUTPUT:

in_funnel  =  0, if SA, CT and p are outside the "funnel"
           =  1, if SA, CT and p are inside the "funnel"
Note. The term "funnel" describes the range of SA, CT and p over which
  the error in the fit of the computationally-efficient 25-term
  expression for density in terms of SA, CT and p was calculated
  (McDougall et al., 2010).
