function sys = intvar(varargin)
%INTVAR Create symbolic integer variable 
%   
%   INTVAR works exactly as SDPVAR, with the only difference that
%   the elements in the variable automatically will be constrained 
%   to be integer when an optimization problem is solved.
%
%   See also SDPVAR, BINVAR, INTEGER, BINARY
