rho(3m)

NAME
rho - Calculate sigma or sigma-theta

SYNOPSIS
s = rho(T, S )

DESCRIPTION
Calculates density anomally sigma or theta sigma. This function was called rho and not sigma because there is already a sigma function in Matlab.

PARAMETERS

P   Vector of pressure (in dbar).

T   Vector of temperature or potential temperature (in deg C).

S   Vector of salinity (in ppm).

RETURNS

s   Sigma (in kg/m^3) relative to 1000.0 kg/m^3.
