You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: sw_pres.m
    path of file: ./repos/tracacode/1911-COAWST/script/mfiles/rutgers/seawater
    
    the code of the file until where you have to start completion: function pres = sw_pres(DEPTH,LAT)

% SW_PRES    Pressure from depth

% USAGE:  pres = sw_pres(depth,lat)
%
% DESCRIPTION:
%    Calculates pressure in dbars from depth in meters.
%
% INPUT:  (all must have same dimensions)
%   depth = depth [metres]

    
function pres = sw_pres(DEPTH,LAT)

% DESCRIPTION:
%    Calculates pressure in dbars from depth in meters.
%
% INPUT:  (all must have same dimensions)
%   depth = depth [metres]
%   lat   = Latitude in decimal degress north [-90..+90]
%           (LAT may have dimensions 1x1 or 1xn where depth(mxn) )
%
% OUTPUT:
%  pres   = Pressure    [db]
