Detailed Description

the chromo-electr-magnetic field for any SU(n)

Example:

       int nc=3; 
       int box[]={10,8,8,8};
       mdp_lattice lattice(4,box);
       gauge_field U(lattice,nc);
       mdp_site x(lattice);
       U.load("myfield");
       compute_em_field(U);
       forallsites(x)
         for(int mu=0; mu<U.ndim; mu++)
           for(int nu=mu+1; nu<U.ndim; nu++)
             cout << U.em(x,mu,nu) << endl;
    

Note that U.em(x,mu,nu) is and it is a color matrix in SU(nc). is the lattice spacing.
