%   
%   sysred      - Computes for an original continuous- or discrete-time
%                 state-space system (A,B,C,D) a reduced order state-space system
%                 (Ar,Br,Cr,Dr) and the Hankel singular values of the 
%                 ALPHA-stable part.  Various techniques can be used.
%
