function pnet_putvar(con,varargin)
% PNET_PUTVAR - Send matlab variable(s) of any type over PNET connection.
%
% Syntax:
%
%   pnet_putvar(con,variable1,variable2.....)
%
%   Sends matlab variables over a TCP connection. The variablea must
%   be recived with PNET_GETVAR. Can also be used with UDP packets
%   if the variable/variables fits inside an UDP packet.
