PURPOSE

SYNOPSIS

DESCRIPTION

% -*- texinfo -*-
% @deftypefn {Function File} {@var{sys} =} syssub (@var{Gsys}, @var{Hsys})
% Return @math{sys = Gsys - Hsys}.
%
% @strong{Method}
%
% @var{Gsys} and @var{Hsys} are connected in parallel.
% The input vector is connected to both systems; the outputs are
% subtracted.  Returned system names are those of @var{Gsys}.
% @example
