function [decdeg] = degminsec2decdeg(degminsec)
%DEGMINSEC2DECDEG	Convert degree minutes seconds to decimal degrees
%
%   Syntax:
%       decdeg = DEGMINSEC2DECDEG(degminsec)
%
%   Description:
%       Utility to convert latitude and longitude coordinates from degrees 
%		minutes seconds to decimal degrees
%
%   Inputs:
%       degminsec   N-by-3 matrix of coordinates in degrees minutes seconds
%                   with degrees in the first column and minutes in the 
%                   second column, and seconds in the third column
%
%   Outputs:
%       decdeg      N-by-1 vector of coordinates in decimal degrees 
%
%   Examples: 
%       degminsec = [30 29 12; -118 58 59];
%       decdeg = degminsec2decdeg(degminsec)
%       decdeg =
%                 30.4867
%                -118.9831
