%------------------------------------------------------------------
% Description: A three-dimensional linear system, Example 8.6.1 
%------------------------------------------------------------------
   dx = zeros(3,1);   % column
   dx(1) = x(2);
   dx(2) = x(3);
   dx(3) = -2*x(1) - 5*x(2) - 4*x(3);
