Detailed Description

General Wilson-Dirac dslash of arrays.

DSLASH

This routine is specific to Wilson fermions!

Description:

This routine applies the operator D' to Psi, putting the result in Chi.

chi(x) := > U (x) (1 - isign gamma ) psi(x+mu)

/ mu mu

mu=0

  Nd-1

  \    +
 +    >  U  (x-mu) (1 + isign gamma  ) psi(x-mu)
  /    mu                    mu
