Detailed Description

Unpreconditioned Wilson-Dirac operator with parity breaking term.

This routine is specific to Wilson fermions!

                                                 ~      ~+

This subroutine applies the unpreconditioned matrix M or M the std::vector Psi,

               {   ~
               {   M(U) . Psi              if  ISign = PLUS
       Chi  =  {
               {   ~   +
               {   M(U)  . Psi             if  ISign = MINUS

Algorithm:

The kernel for Wilson fermions with a parity breaking term is

 M  =  (d+M) + i*H*gamma_5  - (1/2) D'
