function varargout = size(obj,varargin)
%SIZE Size of serial port object array.  
%
%   D = SIZE(OBJ), for M-by-N serial port object array, OBJ, returns  
%   the two-element row vector D = [M, N] containing the number of 
%   rows and columns in the serial port object array, OBJ.  
%
%   [M,N] = SIZE(OBJ) returns the number of rows and columns in separate
%   output variables.  
%
%   [M1,M2,M3,...,MN] = SIZE(OBJ) returns the length of the first N 
%   dimensions of OBJ.
%
%   M = SIZE(OBJ,DIM) returns the length of the dimension specified by 
%   the scalar DIM. For example, SIZE(OBJ,1) returns the number of rows.
%
