function sys = parvar(varargin)
%PARVAR Create symbolic parametric variable 
%   
%   PAPRVAR works exactly as SDPVAR, with the only difference that
%   the elements in the variable automatically will be defined
%   as parametric variables (for a multi-parametric program)

%   See also PARAMETRIC, INTVAR, BINVAR, SDPVAR, BINARY, INTEGER
